Can I SNAT UDP traffic using iRule? [for outbound traffic]

Hello Folks,   Can I SNAT UDP (precisely SNMP) using iRule? If yes, could you please share an example how?   Thank you, Darshan

Sorry, I think I didn't explain the exact requirement.

I have 3 IP addresses which I want to SNAT, only for ICMP and SNMP for outbound connection.

I made a rule as following which doesn't seem effective, not sure why.

when CLIENT_ACCEPTED {
   if { ([IP::addr [IP::client_addr] equals 10.254.47.12/32] or [IP::addr [IP::client_addr] equals 10.254.47.13/32]) and [TCP::local_port] == 161 }{
      snat 10.254.55.65
   }
else
{
forward
}
}
