Tomato vpn bridged to adsl pppoa router

[kraigtoft]

Please help me as I'm wanting to find a way to connect tomato router to my adsl2+ pppoa modem. The modem supports bridge mode but can't seem to get the tomato router setup to work along side it.

The setup I would like is to have my vpn setup on tomato router and have ideally all traffic to go through it before modem. But at least would like to have my 3 android boxes connected to tomato via ethernet through vpn and out.

Is this possible. I'm stumped trying. A bit over my head with the whole thing. A nice walk through would be good. I have read it might have to be double nat with dmz setup.


Thanks in advance

The simplest might be the DMZ and double nat option. You might be able to just plug the second router into the adsl router and do nothing.

Double nat main issue is related to game console that host games. They need UPnP and that does not work behind double nat. Double nat also makes port forwarding rules more complex. The DMZ hides one level of port forwarding.

I run a vpn router behind my main router with no special setup and it has no issues at all with the double nat.

If you really want to run in bridged mode you need to configure your tomato router wan port to use PPPoE and get the userid/password either from your dsl router or ask your ISP.

Thanks for quick response. So basically I can plug wan port to lan port and select dhcp on tomato router. Would it need its own ip address. How would I I know if the Android boxes are going through the vpn.

Sorry for ask the questions. What up do I put in dmz of modem and tomato router.

I would disable the wifi on the main router so the android device had to connect to your vpn router. By default the vpn client is setup to force all traffic though the vpn. You have to actually put in special exception/routes to allow some sites or machine to bypass the vpn tunnel.

Hi again Bill

I have it connected up both routers and seems to be working ok. I have put vpn routers ip in modems dmz. Only problem I'm having is the router shows 2 Ethernet cables connected but only 1 port is getting the routers ip. 192.168.2.xxx. I did change the routers ip to log in easier. The lan ports are greyed out in routing settings. Any idea please

Thanks

Its been a while since I used a tomato image. I think it greys them out because they all...at least from the layer 3 standpoint.. represent a single interface. All the lan ports are in the same vlan. On these third party images you can do all kinds of fancy things like put ports on separate vlans and assign different ip to each.

Thanks

I'll look into setting up vlans for the rest.im sure the lan1 lan2 ports where greyed out in there also. Thanks for all your help it's really appreciated.
