Routing is not going to help here, it only handles the network layer, IP,
not the upper layer protocols, TCP and UDP.
You can use TCP wrappers (I would think that AIX has one distributed with
it) to secure your telnet access, but SNMP is based on UDP and won't be
protected by this. You can protect your SNMP data by creating 'public'
and 'private' community names (passwords) that are fairly cryptic, but I
believe that these community names are passed in plain text so be careful
not to have them sniffed; or have ANY password sniffed for that matter.
