Subject: [FW-1] Firewall Routing Issue with SNMP

Current Configuration (sorry about the picture)

                                web servers 10.21.x.x 
                                        |
                                Cisco switch 10.21.x.x (SNMP configured..failing)
                                        |
                                Cisco switch 10.21.x.x (SNMP configured...failing)
                                       |
                                F5 device doing IP forwarding (SNMP configured...working)
                                one interface 10.21.x.x
                                other interface 10.20.x.x
                                       |
                                Cisco switch 10.20.x.x (SNMP configured...working)
                                     
                                firewall (layer 3) (SNMP configured..working)
                                10.20.x.x
                                10.1.x.x
                                      |
                                Bay network Switch 10.1.x.x.
                                      |
                                Server for SNMP traps 10.1.x.x


The devices that are failing are sending traps, and they are getting to their destination.  But it is very sporadic, to the point where some devices are marked as no response inside of my SNMP server.  Is there a configuration inside the firewall (4.1 spk 3 running on IPSO 3.3) that I'm missing.

It gets worse.  This network is load balanced.  The same problems are happening.  Same set of devices are dropping, but  also the second firewall is not sending any traps at all.  It is configured identical to the first firewall...identical.

If anyone has any ideas, I will be happy to listen.

Thanks guys
