Hi i just implemented an edgerouter erpro-8 with the following setup:
eth0: Lan 1 (192.168.1.0/24)
eth0.3: Vlan Co (192.168.3.0/24)
eth1: WAN (190.xx.xx.xx)
eth2.2: Vlan Co2 (192.168.2.x)
eth2.4: Vlan Co3 (192.168.4.x)
I configured NAT, firewall policies and Port forwarding so I can access from ouside an inside server. But when trying to access the same server from inside (through external IP) it just don't work. I checked the Hairpin NAT in the Port Forwarding tab and added the rules. Have rules in WAN_LOCAL and WAN_IN but none of them log the packets. The NAT rules didn't log either as stays in the NAT Hairpin tutorial.
