I have one cisco 2800 runing BGP with my own AS. I have only one ISP.
I have one default route staticly configured to my ISP.
In my router i don't have any filters.
I have an issue that some networks on internet can't ping my servers inside my AS.
Most off all other networks can ping fine, just few big networks such as bellsouth and verisign can't ping my servers.
I've tried a lot of thing, like put source ip in my loopback and ping from it to servers (work), receive default route via bgp, change default route from ip to interface and i didn't have success.
I did a debug ip icmp and see this messages just one that networks try to ping my AS servers:
000366: *Jun 1 23:56:05.815 PCTime: ICMP: time exceeded (time to live)
sent to xx.xx.xx.xx (dest was xx.xx.xx.xx my AS)
I'm trying to figure out how to solve this problem.
Can one help me with this issue ?
