Hi Arno,
I asked the same question about nine months ago. The silence was deafening. ;)
A linux hacker once told me that this sort of thing was possible by using the iptables mangle table to mark the inbound packet based on the inbound interface. Then, somehow, use that to direct the outbound reply. But I don't know if that would really work and I don't have any more details. If you do find a solution, please post it here.

(Please trim inclusions from previous messages) _______________________________________________ Hi,
I am looking for help setting up a conditional routing table.
I have my tunnel up and running. I can reach other 44-net host. amrp-ripd is used to fill the routing table.
So far so good, but I would like one of the web-sites (apache httpd vhost) to be reachable from both 44-net and non-44-net. If i check with tcpdump I see traffic coming in when I try to access the web-site (pi8zaa.ampr.org) via the Internet (I used my phone connected to t-mobile network). But it doesn't work because my server routes the replies to my ISP's Gw where they get source filtered.
Basically I want/need traffic that comes in via the tunnel to get answered from the tunnel interface.
I Googled for a solution. Found lots of variant of this http://tldp.org/HOWTO/Adv-Routing-HOWTO/lartc.rpdb.multiple-links.html but if I understand what is described there correctly, then that is not exactly what I need. Maybe I don't understand iproute2 and its routing table concept correctly. They way I understand it, those examples assume destination routing based on provider subnet, while in my case the destination is on the Internet, and in normal cases should be routed via my ISP except if it came in via the tunnel.
Thanks for any help you can offer.
