Hi everyone,
I've got small LAN, two routers 2600 series one and 1700 series one and laptop computer connected to the 2600 one.
Pings both ways get through fine.

Tracert command produces traceroute from the laptop via 2600 router to 1700 router just fine but when I try to traceroute from 1700 router through 2600 router to laptop it only gets to 2600 router and then I get the stars.

With a help of members of this community(thanks a lot) I discovered that tarceroute on cisco routers sends UDP packets and I did another inbound rule for incoming UDP packets allowing them on all ports (before I had to do one for ICMP Echo Request to be able to allow pings). I even turn the windows firewall completely off but so far had no luck with getting the traceroute command through to laptop. Here is a startup-config on 2600 router, maybe that will help?

Any ideas why doesn't traceroute get through greatly appreciated.
