Hi,

I have the same question.

What about
Internet -> eth1 -> iptables -> Local Process ?

First I thought it should be easy to put a virtual interface in between:

Internet <-> eth1 <-> virtual dev (maybe tun/tap or modified
dummy) <-> local process or routing <-> eth0 <-> LAN

Then I could use egress shaping on eth1 and the virtual device
(and have a setup as simple as a "plain router setup")

But I did not manage to do this yet. Anybody using a setup like this
one? (maybe bridging or iptables -j ROUTE might help? it seems
impossible to force a packet to pass through netfilter for a second time)

Greetings
Jens
