I just want to know about the commands to be used to find out the reverse route issue and to check the traffic flow.
I have a LAN Network behind a Firewall and my firewall is connected to Router and from there i have a connection to my counterpart network Router.
It's Very simple connection and i am not using any NAT Translations. I used only static routes for the above connections. Having a Static route in firewall towards my Router.
In Router, I am having 2 routes:
1. One default route towards my counterpart router.
2. A static reverse route for the LAN Network towards the Firewall interface.
Now the Issue is , my counterpart person haven't added route for my LAN Network and because of this i am not able to ping any of the servers from my LAN Network.
When i am trying to trace route it is getting dropped in my router itself, because of this my counterpart person is saying that the issue is not from my end. As obivious that the reverse route is missing in his router to complete the connections.
Now i need a command to find out that the traffic are hitting out my router and failing in wan interface because of the reverse route issue.So that i can send it to him to prove the same.
Also please help me in providing how the output looks and which parameter we need to check to confirm the issue.
You counterpart's router should have a route to your firewall's inside LAN. If he doesn't then the trace will stop at his equipment.
If in the trace the last hop is his equipment, check that you allow ICMP on your edge ACL
If the trace stops at your router, the next hop should be the firewall interface connected to the router (the outside interface). The ASA blocks pings ( echo-request and echo-reply) by default on outside interfaces, so you'll need to enable it to verify.
We know the problem is because of not having a static router for my LAN Network on the Counterpart Router.
But my query is , I need a command to find out whether the traffic is being transisted in my router on the wan interface or not like "sh conn" or "sh xlate" commands which we use in Cisco ASA where we can find the Flags and other things to find out the root cause.
