Cannot access the router and internal LAN resources remotely

itismo

Hi,

I have tried to solve this before and searched online for a solution but i coudn't find anything useful.

The issue is that after connecting to openVPN server from my router running DD-WRT i cannot access anything in my LAN through internet including the router itself, what i did was a packet capture to see what was really happening and i discovered this: The SYN packets coming from client in the internet reaches the router via my public IP (not the IP assigned via OpenVPN server) which is normal until now, what happens then is that the reply SYN-ACK packet goes through the OpenVPN tunnel and therefore from the client point of view the SYN-ACK packet is out of state.

Is there a solution to make the OpenVPN stateful? Meaning that when it recieves a SYN from a client in the internet to the public IP it should respond to the session using the same destination public IP so a proper TCP session can be established?

Thanks,
Mohamed

This is not normal. If you are trying to reach hosts in your private LAN
all packets should emanate from the TUN device and not be seen by the WAN device.
