encounter problems on accessing the router via telnet from Internet when NAT is applied to the WAN interface of the router. The access-list that tied to the NAT statement has already permit all traffic to pass thru.
I have tried adding the command "transport input telnet" under line vty 0 4 section but still couldn't work. Check on the "show ip nat trans" and is able to see translations taking place for the telnet session but just couldn't establish further; always get connection error on the client side.
The acl that is tied to NAT should not permit all traffic. By using a permit any, you will cause the router to translate packets that should not be translated which will lead to various problems such as not being able to telnet in or high cpu. You should specify which subnets you want to translate.
If you console into your router, change the acl from permit any to permit x.x.x.x, then clear the nat table, you will then be able to telnet into your router.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
