Hey guys,

My son plays Minecraft with his friends and had me set up a server for him on our old crappy ATT Netgear 7550 router. I recently bought an ASUS RT-N56u wireless-n dual band router and as great of a router that it is, I have not been able to forward the same port on it through it's virtual server/port forwarding interface. Here's some info:
-I have a static IP
-Router is set to channel 11 (auto was causing connectivity problems)
-I am using the old ATT modem/router as a modem with wireless disabled so as not to have another network (the Netgear 7550)
-My router is dual band with seperate SSIDs and passwords for 2.4 and 5GHz
-Port I am trying to forward is 25565 on both TCP and UDP protocols

So basically I set up the forward to cover both protocols following the guide for my router and minecraft on portforwarding.com with my static IP, but when I check with portforwarding.com's downloadable TCP/UDP checker on the client computer, it always comes back as unreachable without being able to ping the router. I have also tried running the Minecraft server client but my son says nobody can join the server. I have tried setting protocol as BOTH (which basically allows a single exception to cover both TCP and UDP in one forward) and as TCP and UDP in seperate exceptions, but it does not make a difference. (Yes, I have hit the 'apply' button) I have also created inbound and outbound rules for both protocols on the correct port with maximum leniency in firewall (allows domain and public connections even if not using IPsec). I have never had a problem like this with forwarding before so if anyone has even a shred of insight, it will be much appreciated. That way my son can get off my *** too!

Thanks,
Nintendork

Yes if you want to you can make the Asus an access point. To do this leave your Dlink as your main router and let it do the port fowarding and DHCP. Turn the DHCP off on your Asus. Then instead of plugging in the cable from the LAN port on the Dlink to the WAN port on the Asus, you plug the cable in from the LAN port of the Dlink to the LAN port of your Asus. Then you may have to reboot your devices connected by wires to your router, and reattach your wireless clients and all should work.

Abailey-

First, thanks! Second, the 7550 does not have bridge mode. I was trying to do this but ended up disabling wireless as a stand in. It also explains why I could port forward on te 7550. Because it had a modem built in, there were no devices in front of it to block connection.

Since I have no bridge, could you detail how to set up DMZ correctly or point me to a guide? If that fails I have a slink modem that I can put in bridge, but its a little iffy on connection (this might be because it is er to auto channel instead of 11, so if DMZ doesn't work I can try that.)

Thanks!
(Normally I would reply instead of post as answer but I can't find the button for it on my Note 3)

Not real familiar with the 7550, but see if this works:
bridge modem.
1.Open browser (IE) type 192.168.1.1
2.user: admin password: password
3.Select My network select Network connection (to the left )
4.Broadband connection ( select the tab under action )
5.Look under Vc’s select the tab under edit column. ( to the right )
6.Under Protocol: Set to bridge
7.bridge mode: bridge.

Turn off DHCP
1.network connection
2.Lan
3.private lan the first one.
Uncheck the first option under DHCP.

I put in the drink and set up bridge but have not been able to get Internet connection. I have unplugged it to reset, but if that does not work, should I try dmz?

If you can get bridge mode to work that is better (cleaner and faster). But if you cannot get bridge mode to work you can try DMZ. I am not sure how to define a DMZ on that router. DMZ should work, it is just that instead of the 7550 just fowarding the traffic to your ASUS (bridge mode), it has to process the signal to make the DMZ work.

Im a bit confused now... I set up the dlink to bridge (by the way, disabling DHCP totally shuts me out and makes me reset.) Should ASUS be in bridge too? I can now ping my router through PFPortChecker but the ports are still closed.

No, sorry I confused you. I was not real clear. The dlink should be in bridge mode, not the Asus. Ok on the Asus WAN interface, when you go into the Asus configuration, what IP address is it reporting? Just tell me the first 3 digits as it could be unsafe to give the entire IP Address out on this forum!

first 3 digits are the standard 192.***.*.***. I am forwarding with my local ip as my IPv4 address found in ipconfig /all.

What we need to see is if your IP address of your WAN interface on the Asus is getting the correct IP from your ISP. You will have to go into the Asus router configuration to see this IP address. If you go into the Asus management program and it is showing its WAN address as a 192 number then that is a problem. That means your dlink is still not in true bridge mode. Also, it is not uncommon for you to loose the ability to manage a device once it is in bridge mode (as there is nothing to manage at that point).

Sorry im not really following. If you want my external ip it starts as 75.57.***.*** Basically my router is in autoIP mode because PPPoE does not work for me (Trust me, ive called customer support, they told me autoIP)

EDIT: Here's my config for my modem:

Yes we have to get that 75.57 address to your Asus router or your port foward will not work. The 2 ways to get that address to the Asus router is either through bridging the ATT 7550 so that it passes the 75.57 address to the Asus "unfiltered" or through setting the Asus up in a DMZ on the ATT 7550 router, thus passing the 75.57 address to the Asus "filtered somewhat". Your Asus WAN port should be in AutoIP mode (DHCP) and should get the 75.57 address from your ATT 7550 gateway.

Ok Im following now. Basically I can set my modem as a static WAN IP. Im guessing the static WAN IP should be set to whatever my external is?

EDIT: Setting my modem to static IP disconnected the internet but I think I get it now. figure out the IP my modem is using, set to static IP in the router, apply that IP. Would the modem's WAN IP be the same as my external?

EDIT EDIT: Argh so I found my WAN ip in my router, it still starts with 192.168.*.* so obviously something is wrong. Again I am no longer using the 7550, it doesnt have bridge or DMZ. I am using a D-Link 2540B.

No don't static the WAN. Your ATT 7550 should give your Asus your WAN IP (Your Asus should pick up the address in DHCP mode (Which on the Asus router is WAN Connection TYPE = AutomaticIP and WAN IP Setting = Get the WAN IP automatically YES). If your Asus is not getting that address then your ATT 7550 is not passing it through correctly and making it static on the Asus will not help.

Yes so so my WAN IP is 192.168.*.* but my modem (The dlink not the 7550) is showing 75.57.***.**. any idea on how to sync these?

It would appear that the modem/router is still acting as a router and bridge didnt work. That may be because there is a PPPoE connection set up next to the bridge but if I remove the PPPoE I can no longer connect to the internet through either modem or router.

Wait. you have 3 routers? The ATT 7550, a Dlink, and an Asus?

Ok if you put the Dlink in bridge more and disable its DHCP server, it should hand off the outside address to your Asus. If it does not, then it is possible that when in bridge mode it will not do the PPPoE and that info and setting would have to be done on the Asus. I am trying to find info on the Dlink but I cannot find much.

The only problem is I have tried to turn of DHCP and it has resulted in no internet at all. I will try that as a last resort, but would it work to have the ASUS as an access point? The ASUS has really good coverage and can get up to 300Mbs on my computer (no joke) but since my connection from at&t is consistently 5mbs, it wouldn't really matter. Basically what I am trying to say is that if I port forward on the modem while the clients connect to the asus as an access point, would that work. (I want to keep the good connection to the asus router while relying on the dlink to do the grunt work)

Alright router is in AP mode and dlink is port forwarded correctly but still the ports are closed. Ill try using the 7550 since ive had success port forwarding that but Im not sure what good itll do.

YEP! The 7550 solved the problem. I think the dlink is just too picky and I felt like I couldn't really get a handle on it, so it's time to retire it. Thanks for all your help abailey, you obviously get best answer!
