Hi,

I'm not sure how you can telnet one way but not another. The answer appears to be the fact that both s0/3/0:0 are int different subnets.

i.e.

Subnet 1

R1 IP: ip address 10.99.4.106 255.255.255.252

Usable addresses in this subnet 10.99.4.105 & 106

R2 IP: ip address 10.99.4.106 255.255.255.252

Usable Addresses in this subnet 10.99.4.109 & 110

I am assuming that these are on the same link as there is no routeing to suggest otherwise.

HTH - please rate if it does.

Regards

Stephen

Check your access-list 23. You have one on R2 but not on R1. It seems that the ACL on R2 is preventing access.

Hi,

On router 2 , remove the access list from the line vty, it will work

line vty 0 4

no access-class 23 in

+++++++++++++++++++++++++++++++++++++++++++++

Also you could modify the access-list 23 to allow R1 IP.
