Netview 7.1.3 on AIX 4.3.3

Nmdemandpoll and ping are successful from the Netview server (server1) to a router, but snmpwalk fails. Router is behind a firewall. All snmp parameters are set correctly on the router, including the access list. Another Netview server (server2) sitting on the same subnet as the router is able to snmpwalk the router fine.

Ovobjprint on the router from server1 shows (among other things):

14 OVW Maps Exists 1
15 OVW Maps Managed 1
57 SNMPAgent Unset(0)
82 IP Status Normal(2)
85 isIPRouter FALSE
112 vendor Unset(0)
124 isNode TRUE
126 isComputer TRUE
127 isConnector FALSE
128 isBridge FALSE
129 isRouter FALSE

[notice the SNMP Agent Unset(0) and isRouter FALSE fields]

Ovobjprint on the router from server2 shows (among other things):

14 OVW Maps Exists 1
15 OVW Maps Managed 1
57 SNMPAgent Cisco Router(3)
82 IP Status Normal(2)
85 isIPRouter TRUE
112 vendor cisco Systems(12)
124 isNode TRUE
126 isComputer TRUE
127 isConnector TRUE
128 isBridge FALSE
129 isRouter TRUE

Before I go jumping on the firewall people, is there something I can try to ensure it is a firewall issue?
