2 NICs 1 SRCDS

[FL0WL0W]

Here is my situation. I have 1 NIC that connects directly to my ISP and the other is acting as a gateway (Through ICS) for my Internal network.

1. If i connect from internal to the server noone else can join.
2. if i don't connect to the server everyone can join just fine but if i connect from internal everyone looses connection.

I'm pretty sure it is because the server is switching traffic over from the NIC connected to the internet to the NIC connected to my internal lan. Is there anyway i can fix this? possibly with a virtual NIC connected to the internal network, but i don't know how to do that.

im running the same setup. change the ports on the machines on your internal network to use something other than 27005, 27015

I fixed it. what i did is i set it up to the ip of the NIC that was connected to my internal network. in my case 192.168.137.1 and then i added the role "network policy and access services" and added NAT to the NIC connected to my ISP and added the port to forward to 192.168.137.1. The only thing is i have to connect to my internal ip and others cannot connect to me but i already knew that from the other servers i've run in the past.
