Problem getting to websites - via NAT Qwest modem
I have a site-A and a site-B.
Site-B working just fine with an openvpn server and it is using PPPoE to authenticate, the modem is in bridge mode.
On the site-A, the pfsense box is in a DMZ via the DSL modem. That was the only thing I changed on the modem. The modem has a static IP on its WAN side and forwarding everything to a private IP on the pfsense WAN port. There is a VPN tunnel between the two and that is working 100%. The problem is that site-A web browsing stinks and pages timeout all of the time. Some web pages you just plain cannot reach. I have full firewall logging on and everything is going out free and clear. I believe the problem is due to the double NAT. Internet pipe is 7 megabit connection on site-A.
What are my options? I notice on the qwest DSL that I can disable NAT and I can enable dynamic routing. What can I do to get this working by keeping the NAT on the modem?
1. I know I can reconfigure and use PPPoE on pfsense and bridge the router. (I am scared to do this because last year I was using 2.0 RC2 on this box and it kept dropping the internet when using PPPoE. That is why I am even NATTED in the first place. I just upgraded it to 2.0.1 last night.
Highly unlikely it's because of double NAT in itself. My first guess given it's DSL and with that description is you probably need MSS clamping to a lower value on the modem, it should have that configurable somewhere.
Thanks, I will look into that.
