Duh! I'm not thinking straight this morning. Get rid of the 'tcp' from
all of these entries as well, otherwise I think you'll lose every
other protocol in the implicit drop rule :<

Ascend-Data-Filter = "ip in forward dstip 1.2.3.4/32 dstport = 25"
Ascend-Data-Filter = "ip out forward srcip 1.2.3.4/32 srcport = 25"
Ascend-Data-Filter = "ip in forward dstport != 25"
Ascend-Data-Filter = "ip out forward srcport != 25"
