I have a 5250 telnet session open to an iSeries. When I do this from the
LAN (to the DMZ), I can keep the connection idle for hours without it
being reset by the iSeries.
When I connect to the iSeries (5250) from a remote site over the VPN
(IPSec) the iSeries resets the connection after less than 15 minutes of
idle time. The VPN goes over a cable network.
Now I enable SO_KEEPALIVE when I connect from the remote site and that
seems to work (no resets when being idle). But my question is, why do I
get these resets in the first place?
You can point me to RFC's, manpages, docs, tips, hints, ... anything. I
would appreciate it a lot. I guess this is not really an OpenBSD
question because I think it has nothing to do with the VPN (I can't
imagine).
Regards,
Tom
