![]() Inet6 fe80::1%lo0 prefixlen 64 scopeid 0x7Īlso so we are sure. You do show your lo up and on 127.0.0.1? with an ifconfig lo0: flags=8049 metric 4 Pass out on lo0 inet6 all flags S/SA keep state label "pass IPv6 loopback" From WG4R3 I cant ping Lo0 and Lo1 on WG4R2 and vice and versa. Pass in on lo0 inet6 all flags S/SA keep state label "pass IPv6 loopback" 1 Accepted Solution Solved: Hi, can you help me with this. Pass out on lo0 inet all flags S/SA keep state label "pass IPv4 loopback" Pass in on lo0 inet all flags S/SA keep state label "pass IPv4 loopback" So here example you see me doing that above test while doing a packet capture on localhost for my port 8443įor grins check your loopback rules pfctl -sr | grep loopback So you can actually see the connection attempt, and the source IP, etc. * SSL certificate problem: self signed certificate in certificate chainĬurl: (60) SSL certificate problem: self signed certificate in certificate chainĪlso sniff on the localhost while you try and do your test. * TLSv1.2 (OUT), TLS alert, unknown CA (560): Specify the range of Loopback IP Address According to the reserved range for Loopback IP addresses. * TLSv1.2 (IN), TLS handshake, Certificate (11): * TLSv1.2 (IN), TLS handshake, Server hello (2): * TLSv1.2 (OUT), TLS handshake, Client hello (1): * TLSv1.2 (OUT), TLS header, Certificate Status (22): * CAfile: /usr/local/share/certs/ca-root-nss.crt * Cipher selection: successfully set certificate verify locations: That address is always 127.0.0. an ip-address that is not part of 10.0.0.0/24) and set a static route on your asa via the ip-address of the ethernet of the device with the loopback-address. If you cant successfully ping your router, but your router appears to be turned on and working, you can try pinging whats known as a loopback address. Lets see the output of your curl with the -v so we can see exactly what is going on. To see, if that is the reason for your issue, please configure the loopback-interface with an ip-address, that is not directly connected to the ethernet-interface of your asa (i.e. on mine for example ps -ax | grep 82772Ĩ2772 - Is 0:00.00 nginx: master process /usr/local/sbin/nginx -c /var/etc/nf (nginx)Īgain there is no firewall rule that would prevent access to itself. Thanks in advance to anyone who will take the time to help me.Those are the pids of the processes, 2 workers and the main one. ![]() Because it's a stateful FW, I normaly don't have to setup a out direction rule, so. I don't know what I'm doing wrong but it's dosen't work. My ultimate goal is to ping lo0:192.20.11.1 on router 'Good'. I advertise the respective networks Lo0 and Lo1 via OSPF, so I am not sure if I can understand whats going on. I have setup a rule like that in the WAN Rules section :Įven if I do like that it's not working : 06-01-2009 05:58 PM - edited 03-04-2019 04:57 AM. I want to use this loopback interface to do many things, but at first I want to ping it from anywhere, and I don't know why, but I can't manahe to do it. So that means you do not need a NIC to be able to ping your loopback addresses. Each host in your network deployment should have a unique loopback interface address. To configure a loopback interface: Using the host IP address, assign it to the loopback interface. This procedure uses a group called global as an example. The loopback interface allows IT professionals to test IP software without worrying about broken or corrupted drivers or hardware. This is a recommended best practice for configuring the loopback interface. PING 1.1.1.1 (1.1.1.1) from 51.xx.28.203: 56 data bytesĦ4 bytes from 1.1.1.1: icmp_seq=0 ttl=53 time=4.929 msĦ4 bytes from 1.1.1.1: icmp_seq=1 ttl=53 time=4.935 msĦ4 bytes from 1.1.1.1: icmp_seq=2 ttl=53 time=4.961 ms The loopback interface has no hardware associated with it, and it is not physically connected to a network. From this interface I can ping my gateway and internet (no problem with # ping -S 51.xx.xx.203 1.1.1.1 ![]() I have setup correctly an public IP to my Lo1 interface. Using the below host file pinging the computer name or localhost will always return an IPv4 address, which fixes the problem with the 3rd party software localhost name resolution is handled within DNS itself. I don't know if someone can help me but, I'm facing a problem.
