I have a Router that runs DD-WRT and a OpenVPN Client that connects and redirects every request over the VPN. My VPN provider supports port forwards, the problem is my router does not forward anything that comes in over the OpenVPN connection (tun1 im my case) (the rules set in the port forwarding Web-UI only apply to incomming WAN requests)
Basically what I want is to set port forwards for requests that come in from tun1 to specific local ips. (like forward everything from tun1 that comes on port 443 to ip 192.168.3.2). Could anybody give me a hint how such a rule can look?
Her is my ifconfig if that helps
