10.1.10. More Pipe Examples
VoIP to the remote site is guaranteed 500 kbps of capacity before it is forced to best effort.
SAT with Pipes
If SAT is being used, for example with a web server or ftp server, that traffic also needs to be forced
into pipes or it will escape traffic shaping and ruin the planned quality of service. In addition, server
traffic is initiated from the outside so the order of pipes needs to be reversed: the forward pipe is the
in-pipe and the return pipe is the out-pipe.
A simple solution is to put a "catch-all-inbound" rule at the bottom of the pipe rule. However, the
external interface (wan) should be the source interface to avoid putting into pipes traffic that is
coming from the inside and going to the external IP address. This last rule will therefore be:
Rule
Name
all-in
Forward Return Source
Pipes Pipes Interface
in-pipe out-pipe wan
Note: SAT and ARPed IP Addresses
If the SAT is from an ARPed IP address, the wan interface needs to be the destination.
