Would anyone know how to get this functionality? Thanks in advance. ![]() The IP addresses of the loopback interface are 127.0.0.1 and ::1 in IPv4 and IPv6, respectively. If the loopback interface replies to ping messages, the TCP/IP protocol stack is properly configured. I tried to set this up using port forwarding in LuCI, but it doesn't seem to work. To test whether the TCP/IP stack is properly implemented on the local system, you can send a ping request to the loopback interface. In the scenario that I would want, all traffic from LAN to my public IP would be forwarded to the router itself (destination IP changed to 127.0.0.1), which would then redistribute it based on port forwarding rules, UPnP etc. Use PING to create a time delay: Create a delay of 1 or more seconds by pinging the loopback address (127.0.0.1) multiple times. The problem is that in my network configuration, the OpenWRT router doesn't have the public IP assigned to its WAN interface, because it sits behind an ISP router with 1:1 NAT.įrom my understanding, that means that it can't know that traffic to this public IP is in fact destined towards it, and proceeds to route it to the ISP router, which probably throws it away. 4) Ping the IP address of a remote host to verify that you can communicate through a router. from phone carrier), it works as it should, but the request times out if I try to do it from within.įrom searching on the internet, it seems that this problem is quite common, and the solution always is to enable some loopback/reflection of router WAN IP to LAN. Host loopback refers to the fact that no data packet addressed to 127.0.0. If I try to ping/access some service on my public IP from outside of LAN (i.e. ![]() I recently got a new ISP and I am now facing an issue with accessing my own (static) public IP from within the network.
