Team,
I'm unable to remotely (WAN interface) access this Cisco C891F router using the underneath config.
telnet and ssh both works using the LAN interface. the error message is get is "Connections refused"
With debug ip packet i do see an RST packet as a response to the incoming telnet request packet.
Current configuration : 9161 bytes

Any help is highly appreciated.
Thanks in advance, Willem

Try turn off the aaa for a minute no aaa new-model
set standard username/password ---username Willem secret xxxxx
Then under line vty 0 4 apply ----login local
thsat should work for you , did you generate crypto keys for the ssh ?

Mark,,
I have done as suggested.. No results..I believe it is related to either a NAT or routing issue (bug).
I have also delete the vlan 6 interface as that one was not required any more.
I have about same config, a little different router, older IOS and that one works.
Still looking for a solution.

We ran into bug CSCup75103.
Symptom:
On IOS upgrade to 153-3.M2.bin & onwards, we cannot telnet/ssh the router where nat is configured.
Conditions:
This problem only exists if we have nat entry configured using ip which also exist on an interface, i.e
ip nat inside source static tcp
Workaround:
change the above statement to use interface instead of ip address, i.e
ip nat inside source static tcp
Upgrade to 15.4(3)M4 solved the problem.
