To establish a reverse Telnet session to an asynchronous line, determine the IP address of your LAN (Ethernet) interface or loopback address, then enter a Telnet command to port 2000 + n on the access server, where n is the installed asynchronous line number. For example, to connect to the console of the router attached to line 1 (which is really asynchronous line 20)-
router# telnet 172.16.1.10 2020
Trying 172.16.1.10, 2020 ... Open
The 2000 is something decided to use and AFAIK you can't change it.
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
