Snmptrap not forwarding on proper port

All,

Good afternoon. Not sure what I did wrong as had setup snmptrapd.conf to forward all traps on port 162. However, the far end machine is only receiving snmp on port 161:

Forwarding From:
---------------------
[root@xxx /usr/local/etc/rc.d]# vi /etc/snmptrapd.conf
disableAuthorization yes
authCommunity net public forward default udp:10.1.1.227:162 public

[root@xxx /usr/local/etc/rc.d]# cat /etc/snmpd.conf
rocommunity public
rocommunity public localhost 
trapsink  localhost public 162
trap2sink  localhost public 162
trap2sink  10.1.1.227 public 162
trapcommunity  public
master yes


Forwarding To:
---------------------
[root@yyy]# tcpdump -i eth0 -vvXX -s 65000 host 10.1.1.234 
tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65000 bytes
18:06:37.048444 IP (tos 0x0, ttl  64, id 64304, offset 0, flags [none], proto: UDP (17), length: 137) 10.1.1.234.12736 > 10.1.1.227.snmp: [udp sum ok]  { SNMPv2c { V2Trap(94) R=695320953  system.sysUpTime.0=111727570 S:1.1.4.1.0=E:2021.14.1.1 system.sysLocation.0="where did this trap go" } } 

[root@yyy ~]# tcpdump -i eth0 -vvXX -s 65000 port 162
+tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 65000 bytes
0 packets captured
2 packets received by filter
0 packets dropped by kernel

Any ideas as to what is setup incorrectly? Thanks.

Sincerely,
George
