Telnet/SSH access

Unanswered Question
Jun 7th, 2010

I am unable to telnet or ssh to a router from internet (LAN works fine). I see following in debug logs on the router

*Jun  7 12:19:22: TCP0: state was LISTEN -> SYNRCVD [22 -> <Outside IP removed>(59121)]
*Jun  7 12:19:22: TCP: tcb 85455EE8 connection to <Outside IP removed>:59121, peer MSS 1260, MSS is 516
*Jun  7 12:19:22: TCP: sending SYN, seq 1340633744, ack 114092318
*Jun  7 12:19:22: TCP0: Connection to <Outside IP removed>:59121, advertising MSS 536
*Jun  7 12:19:22: TCP0: RST received, Closing connection
*Jun  7 12:19:22: TCP0: state was SYNRCVD -> CLOSED [22 -> <Outside IP removed>(59121)]
*Jun  7 12:19:22: tcp0: T CLOSED <Outside IP removed>:59121 <Telnet Host IP removed>:22 early close
*Jun  7 12:19:22: TCB 0x85455EE8 destroyed

Is it something to do with mss?

Any help would be greatly appreciated.
