Actually, incoming and outgoing are often/usually controlled by totally
different mechanisms.
For example, how are you doing load balancing? By having the Cisco throw
packets alternately out each port? By having it do so on a connection-
oriented basis ('ip route-cache' as opposed to 'no ip route-cache')?
Or do you take full or partial routes from your providers?

I think in general the most appropriate thing is to first contact
the NOC for ASN 3838 (Structured Network Systems). Or since it's
not cutting you off from the net, send e-mail to [email protected]
[info gleaned from the whois records].
But I see only one route for you. The tail of the AS-Path is
1239 1792 3130 5798.
Perhaps you're not sending 192.108.254.0/24 to AS 3838?
Or they've filtered it?
