11:18.54cityLightshi
11:19.03cityLightsI need help with source level routing
11:20.02cityLightsassuming I got eth0 from which I establish l2tp and get ppp0 , which supplies the dafult gateway, how can I answer traffic coming in to eth0 from eth0?

12:46.04antiphaseRouting is all about destinations unfortunately
12:47.15morsingUnless you do source routing...
13:01.55halil2tp? arp should take care of that
13:02.54halilayer2 vpn's are always a bit of a hassle, dmvpn or something with dynamic routing is always easier
13:09.10antiphaseISTR that there was a reason for all the rigmarole, involving the need for bridging to carry broadcast traffic etc.
13:16.21halii always find it interesting that people think layer 2 networking is easier than layer 3 and routing stuff properly
13:16.48haliwhen layer 2 is always prone to fuckups when doing complex stuff, with stuff like spanning-tree breaking etc
13:33.04cityLightsdoes source based routing mean: if you get traffic from a certian IP address answer using this device?
13:41.02antiphaseNo. It's a deprecated method of routing where the sender of a packet may specify the route to the destination
13:41.42antiphaseIt's a huge security risk and you're unlikely ever to see it enabled except by accident
13:42.33antiphaseIf you want to originate packets from specific interfaces, then you need to have a route to the destination which specifies that interface
13:43.26antiphaseOtherwise, your traffic will leave by the most specific route to that destination according to the routes you do have available, or the default route if there isn't one

20:58.21cityLightscan I say "any communication coming in via port 1234 will be answered via eth0?
