![]() Thanks again for all the input RIP: sending v2 update to 224.0.0.9 via Ethernet0 (192.168.1.130) RIP: sending v2 update to 224.0.0.9 via Loopback0 (10.1.1. Would anyone know how to get this functionality? Thanks in advance. Since I dont have PPP setup, Im guessing the RIP advertisements are being dropped and routers 2 and 3 simply have nothing to advertise to or receiv from. 0.0.0.0, on the other hand, is more of a wildcard than a specific location. As such, youll typically enter it when telling the software to connect to a server either via a web browser or a game. I tried to set this up using port forwarding in LuCI, but it doesn't seem to work. 127.0.0.1 is a signal to your computers TCP/IP that you dont want to connect to the internet you want to connect to a server on your own computer. 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. 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. ![]() 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. If I try to ping/access some service on my public IP from outside of LAN (i.e. The devices are already connected via an Ethernet cord and despite the fact that, if the Switch goes through to the Router, it can reach the internet, the host PC is not able to ping the loopback address at all. Type STRTCP (Start TCP/IP) at the command line.I recently got a new ISP and I am now facing an issue with accessing my own (static) public IP from within the network. So Im attempting to configure a loopback address on my Cisco cat-3850 Switch to be pingable on a host PC. Scroll down to find the loopback interface (127.0.0.1 or ::1), and select option 9 (Start) from the Work with TCP/IP interface status menu.Or select option 4 (Work with IPv6 interface status) for IPv6 interfaces. Select option 1 (Work with TCP/IP interface status) for IPv4 interfaces,.Verify that the host table contains an entry for the LOOPBACK host name and IP address 127.0.0.1.Select option 10 (Work with TCP/IP Host Table Entries).At the command line, type CFGTCP (Configure TCP/IP).This is only relevant for IPv4 because host tables do not currently support IPv6. You need to add the entry to the host table. Recovery The local host table does not have an entry for the IPv4 LOOPBACK host name and IP address of 127.0.0.1. Failures might indicate the following problems.Prompt on the PING command by selecting F4 for complete details on the PING parameters. For IPv6: PING '::1' See PING parameters to fine-tune the PING command to get the most accurate results.For IPv4: PING '127.0.0.1' or PING LOOPBACK.At the command line, type these commands:.To ping the loopback interface on your system to troubleshoot the problem, follow these steps: However, you can use a Domain Name System (DNS) to store the IPv6 host name instead of using the local host table. The IPv6 loopback interface does not have a corresponding host name because the local host tables do not currently support IPv6 addresses. Similarly for IPv6, i5/OS reserves the IP address ::1 and the line description *LOOPBACK for this purpose. That being the case then as each router reloads they will use the same RID and not exchange routes. I5/OS ® reserves the IP address 127.0.0.1, the host name LOOPBACK, and the line description value of *LOOPBACK for verifying the software. If this loopback happens to be the highest IP address and the RID of EIGRP has not been configured then EIGRP will use that (upon next reload). ![]() You can perform the test without being connected to a physical line or network. Started, and working properly, ping the loopback interface. You should get a reply in the Command Prompt, which looks like this: Pinging 151.101.194. To verify that your TCP/IP software is installed, To do this, open the Command Prompt and use the following command to ping your original IP address, but type 'ping -6' to isolate the IPv6 line. Pinging the loopback interface on your system
