NethServer 6

Until now it is possibile to force specific traffic from LANs to a specific provider using tc prop to set shorewall tcrules file.

It would be use to manage this property also for the traffic originating from the server itself (e.g. nethserver act like a mail server and must send through a specific internet connection) .

Shorewall make it possibile using a sligtlhy different syntax for this type of traffic:

#ACTION         SOURCE          DEST            PROTO   PORT(S) CLIENT USER    TEST
#                                                               PORT(S)
MARK(2):P       <local network> 0.0.0.0/0       tcp     25
Note that traffic from the firewall itself must be handled in a different rule:

#MARK           SOURCE          DEST            PROTO   PORT(S) CLIENT USER    TEST
#                                                               PORT(S)
MARK(2)         $FW             0.0.0.0/0       tcp     25
