How can i setup route-map for this situation:
On 1841 router i have leased line link to ISP, and ISDN link for special purpose, and user on LAN. (one source to two destination)
Users must be able to access to both link at anytime.
There is picture of logical topology in attachment.
Try to write your ACL like this:
access-list 100 permit ip 10.0.0.0 0.0.0.255 x.x.x.x x.x.x.x(isp net)
access-list 110 permit ip 10.0.0.0 0.0.0.255 192.168.0.0 0.0.255.255(isdn net)
And then try your nat configuration like this:
ip nat inside source list 100 interface f0/0 overload
ip nat inside source list 110 interface bri 0 overload
The point is that you should use extended ACL in specifying nat. However,there is a problem how to specify destination address in the ACLs. Anyone knows?
