Hello, I have a PPTP server (running Windows Server) behind PF (OpenBSD 4.4). I tried 'rdr pass' on 1723/TCP and all GRE traffic, without success. Then, I tried to set up an alias on WAN interface and create a binat rule, doesn't work too.
Is there any limitation with PF? I wouldn't like to use Netfilter (ip_gre module) to solve this problem. Any idea? Thanks in advance,
