I have a DGND3700v2 modem router in front of a FVS318G router. I just replaced the AT&T modem with the DGND3700v2. Internet was slow with the ATT modem but connection was not a real problem. I thought things were OK and then I started having problems connecting to the internet. Line check was OK so I plugged one comptuer directly into the modem and got an internet connection. LAN traffic seems to be OK through the FVS318G if the internet is not a required. I am wondering if the back to back firewalls for both the DGND3700v2 and the FVS318G are for some reason blocking internet access and if I should add a rule to the FVS318G to allow all traffic and effectively disable that firewall. I had back to back firewalls with the ATT modem and the FVS318 and it didn't appear to be a problem.
Any knowledgeable recommendations?
