Re: Access AIX system from different network subnet

That looks like my problem, default gateway. Years ago they used to have this system exposed to the outside world with a gateway of 204.186.115.1. They have since moved the system inside but the gateway was never changed. How do I safely change the default gateway? I'm use to going through SMIT but I know there is a more direct way. Also, it would not surprise me if there is a second IP address on the system (a 204.186.115.x), how would I remove that address and make 172.20.18.2 the one and only IP address.

Telnet. People on the same subnet have been telneting into the system for years. This is the first time someone from a different building (and subnet) is trying to telnet into the AIX system. Everyone is behind the firewall so it shouldn't be a problem. My though is because it is a different subnet, which makes it a different network, that AIX is not accepting the connection.

Looks like your default gateway isn't setup, or not setup properly.
What does "netstat -r" give you ?

Can you ping the default gateway, can you confirm that it is setup as a router.

Also, can you ping the other way around (from the aix box to the clients) ?
What does traceroute tell you ?
