Im having a lot of trouble setting up a NAT statement on my Netgear modem.
My modem IP is 10.1.1.1 and is connected to 10.1.1.2 on my firewall. Behind the firewall I have a LAN or 192.168.1.X. I am trying to NAT one of my static IPs from Comcast to a server on the 192.168.1.X network. When I do add this via 1 to 1 NAT, I get the message Status: Invalid IP Address.
I had to get a new modem today and havent been able to get this working. With my previous modem, it worked.
Hi! Thanks for reaching out. I can help with the internet service concern. Would you mind sending a private message with your full name, the last four digits of your account number, and a phone number linked to the account so I can help?
I also called Comcast support but they werent able to help.
It seems the problem is NAT'ing to an address on a different subnet. I have a route setup to that subnet but that doesnt help. I'm not sure why this worked before on the SMC modem. Is there a different mode or feature that needs enabled?
Jeremy, thank you for all of the information. I am happy to assist with the modem settings. Can you please confirm the address on the account? Can you tell me what the firewall settings are at on the modem?
