I have multiple Layer 3 SVI configured on the core switch and all of them are configured with "ip helper-address" command which by default enables "ip forward-protocol".
Now we have a requirement to add "ip forward-protocol udp PORT#" command.
when using "ip helper-address" then following UDP ports are enabled by default:
4) Netbios name services-137
5)Netbious datagram services-138
What will be the impact of adding "ip forward-protocol udp PORT#"? Will this impact the default ports enabled by the "ip helper-address" method?
