Hi Andrew,
Actually, the case is like this:
1. we have connected to two diff. isp (one primary and one as backup)
2. a cisco router 2600 with fw feature set is conected to the internal
network (ethernet) and on the other side connected to the two isp router
through another ethernet.
3. eigrp is running between the 2600 router and the isp routers, so two
default route with diff. cost is passed to the 2600 router
4. route-map is used in order for correct NAT mapping.
the access list is just like this:
access-list 20 permit 192.168.115.222
(where 192.168.115.222 is the ethernet addr of the isp1 router)
route-map to-isp1 permit 20
match ip next-hop 20
however, after I apply this route-map, I can't ping inside my internal
network (other service working fine e.g. www, telnet, ftp). Is there any
reason for that. I suspect that IP NAT process sequence is diff. when using
'route-map' instead of 'list'. Do you know where in cisco web site I could
checkout in details how route-map + nat is working.
Thanks in adv., Eric
