Description:

Hello!

I'm using pbr to filter all udp packets using my external IP so torrenting can work properly (using direct IP not NAT IP). Simple rule should be fine:

config policy
        option proto 'udp'
        option interface 'wanext'

But it failed with : ERROR: Policy 'Untitled' has no source/destination parameters!

Following rule works fine:

config policy                        
        option dest_port '0-65535'
        option proto 'udp'               
        option interface 'wanext' 

Booth rules should be accepted.

Another issue: when policy name specified, error will be ommited:

ERROR: 
udp routing
