Allowing Netbios 137/138 through ASA

Hello,

I've recently had to move an AS400 system behind an internal ASA firewall and now users are unable to browse to it.

The ASA is running Version 8.2(5)

I get these messages:

Sep 11 2012 17:09:59: %ASA-7-710005: UDP request discarded from 172.19.241.35/137 to outside:172.19.241.255/137

Is there a way to enable these ports without enabling NAT?

No VPN's involved, just an inside and outside eth interfaces
