error when resending traps SNMP

[jorgelina.abraham]

In DFM- Configuration- Other configurations- SNMP trap forwarding,
I put two hostnames for notification (see: DFM trap fwd.jpg)
The SNMP trap receiving use the default port (see.DFM trap receiving.jpg)
And I have a problem with the hostname: 10.78.33.111 port: 262. Do not work (see: cap1.pcap)
With the other hostname: 10.24.0.41 port:162. Work ok (see:cap2.pcap)
I try to change the port from 262 to 162 and work fine, Why?
Exist any limitation about the number of port of SNMP trap forwarding?

Thanks in advance!

This sniffer trace looks fine to me.  What makes you think it's not working?  Are you sure the trap listener on 10.78.33.111 is actually bound to udp/262?
