Has any one seen this issue. We have two circuits coming into a NSA2600 one from Level 3 and one from Spectrum. I can get traffic from outside to our email server on the Level 3 side but I can not on the spectrum side. Please see attached document for an idea of our layout.
If I setup a computer directly connected to Spectrum modem with a public ip address I can ping from the internet. How do I get traffic to flow from the spectrum modem to my firewall with one connection like I have on the Level 3 side.
