Hi,
I have this strange problem with my network and was wondering if anyone might be able to help me out.
Here is my topology:
I have an ADSL modem router (Netcomm NB1300plus4) connecting to the Internet. It's assigned with a static Public IP address.
From my modem router, it is connected to both my mail server and a Netgear router FVS318. Both my mail server and Netgear router are assigned with static Public IP address because I have a block of 8 subnet IP addresses: 69.xxx.xxx.xxx/29 and subnet mask: 255.255.255.248
Then, all my LAN network are sitting behind the Netgear router.
The strange problem I'm getting is that most of the time when I can't access to my mail-server from home (outside my office), I have to reboot my Netgear router. Then, everything is working again. I find this bizarre because the one that I should reboot is the modem router, not the netgear router.
This happens quite regularly which worries me a lot because it causes problem for my staff to be able to check their mails from outside the LAN.
When it happened for the first time, I thought I lost the Internet connection which might be the reason I could not connect to my mail-server from home so I came to the office to restart my modem router (Netcomm). This did not do the trick as I still could not access to my mail-server.
Then, I tried to reboot my Netgear router by accident. To my surprise, everything seemed to work again. I could log into my webmail from both office and home.
I wonder why the problem (if any) with the Netgear router could affect the Internet connection to my mail-server which sits outside the Netgear router.
Any help would be greatly appreciated.
Thank you very much
