External Connection Times Out to Gateway IP
We have been using Pfsense router with NAT rules in place for an outside company to transfer files to a computer on our network. I did all of the port forwarding from their external IP to the internal IP. And using the ports they asked for. No issues with that.
But this became a problem when we moved them to another PfSense router on a different subnet internally. I copied the exact same settings from router 1 to router 2. They continue to get a Connection Timed Out error on the new router.
There is only one difference in equipment: The new router is using Spectrum ISP. Their modem is in Bridge mode with a Static IP address. The original ISP is Megapath, but I don't know if that is setup in Bridge mode, I would assume it is since that one is still connecting to router 1 and works fine.
The Port Forwarding is in place for 443, 80, 8081, 22, among a few other misc ports.
I am using a program called ZenMap on my Mac to see if any ports are blocked. 80 and 443 were blocked when I have a NAT / 1:1 setup, but once I disabled that rule, those ports are no longer on the blocked list.
Is it possible the Spectrum modem is blocking access?
And how else can I test from the outside if the WAN/Gateway is accessible?
