UDP Relay

Post by Cernunnos »

Hello board,

I'm currently working on an issue with the "ip udp relay" option in AOS.

From Cisco I know that when using the "ip helper address" command, by default several udp broadcasts are transmitted to the stated destination ip address. In AOS when using the ip helper <ipaddress> it will only distribute DHCP broadcasts. By using "ip udp relay NBNSNBDD" in AOS I can enable the Netbios UDP relay, but as it turn out, the Netbios traffic is not relayed to the specified ip helper addresses.

Snip of the config (which is used for DHCP relaying, this part is working all right!)
ip helper per-vlan only
ip helper address 10.50.10.20 vlan 20
ip helper address 10.50.10.20 vlan 40
ip helper address 10.50.10.20 vlan 41
ip helper address 10.50.10.20 vlan 60
ip helper address 10.50.10.21 vlan 20
ip helper address 10.50.10.21 vlan 40
ip helper address 10.50.10.21 vlan 41
ip helper address 10.50.10.21 vlan 60
ip helper address 10.50.30.145 vlan 20
ip helper address 10.50.30.145 vlan 40
ip helper address 10.50.30.145 vlan 41
ip helper address 10.50.30.145 vlan 60
ip helper address 10.50.40.255 vlan 20
ip helper forward delay 0
ip helper maximum hops 7
ip udp relay NBNSNBDD
Doing a "show ip udp relay statistics" shows only DHCP relaying, but no Netbios:
Service Vlan Pkts Sent Pkts Recvd
--------------------+--------+-------------+-----------
1:BOOTP/DHCP 993
20 993
20 93
20 993

40 0
40 0
40 0
41 0
41 0
41 0
60 0
60 0
60 0
I simply would like to specify an IP address to which the Netbios broadcast traffic is relayed to, similar to the ip-helper sertup on Cisco devices. Anybody knows, if this is possible?

Thanks in advace!

Kind regards
