I have PPtP client enable on my public interface and I get address from my ISP (DHCP server) 10.10.11.13/32 gateway 10.10.10.1 for pptp interface and also I get IP 192.168.50.114.24 gw 192.168.50.1 at public NIC (interface). My socond NIC(192.168.2.1/24) is local and I have few PC's atached. I'am using masquerading for local addresses behind public one. I have enable GRE and PPTP in firewall/port. Problem is that I can ping anything accept 192.168.50.1 and off course I can not use internet at all. I supose that I must define some firewall rules for pptp at input and forward chain. I try to accept all incoming traffic on public on input and forward chain but nothing.. I see default route in ip/route...
please help !
