Yee,
when you ping serial interface from the router, icmp-echo packets
travel over serial link to the other side where they are forwarded
to your router. Then, your router respond with icmp-echo-response
packets which travel the same path !
To clear this, suppose you have routers A and B on a WAN link:
A <------> B
What is happening is:
1. You start ping on A
2. A send icmp-echo packet to B
3. B forwards packets to A
4. A answers and send echo-response to B
5. B forwards packets to A
6. You got '!' on A
So, access-lists on the other side of the WAN link play a role !
Hope this helps.
