similar to: SNAT based on MAC before routing

Sorry for the long descritpion of the problem, I''d like to know If I misunderstand something or if I meet an intrinsic limit of my setup. 217.58.51.162 HDSL eth1 - SRV_XP: 192.168.254.10 eth0: 192.168.254.1 -----+------------------+------- 81.121.243.250 ADSL eth3 - I want to allow incoming pptp request (port 1723) to be forwarded to srv_xp

Hi, I am trying to categorize the network traffic and to send it out across two different providers. For this I mark the packets in the firewall (in the PREROUTING chain of table mangle), and then use another routing table for the marked packets, which has a different gateway from the main routing table. Basicaly I am following the cookbook example in this page:

Hi, I have a suspicious problem with multiple uplinks configuration.

The wan0 bridge is to allow UPnP works. To allow related

Hello again, I may have a common problem to solve but it seems it is harder than I thought... I have 2 internet providers (each one having a different gateway). Behind the router there are around 100 clients that are SNAT-ed. I want some clients to be SNAT-ed to the first provider, while the others to the second one. The following lines should work: iptables -t nat -A POSTROUTING -s

Hi folks, I have OpenVPN (respect for it developers) running on my FW.

Hello, world! Sorry to subscribe to the list only to immediately ask a question, but this one''s got me scratching my head and I can''t find the answer in the archives, the HOWTO, or on the web. Maybe I''m just asking the wrong question. Anyway, our Internet gateway is a Linux box. We''ve got two Internet feeds, a fast one from a crummy provider, and a

Maybe a strange request, I''ll try to explain this as clearer as I can (forgive my bad english, please :-) ). I''m setting a linux box as a router. My router uses multiple routing tables, so I can address the traffic from specific ip addresses of my lan to distinct ISPs providers (specifying a different default gateway fo r each table), marking packets with iptables

Hi, I have 2 internet connections (1 adsl/1 cable). I am try to route all outgoing mail from the mail server (on the same box), through the ADSL connection routing through the cable will mean mail will get rejected by AOL :( I am using qmail as the mail server. The configuration is: eth0 : cable connection ppp0 : adsl connection eth2 : internal lan connection I have configured split access as

Hello, Is there a way to route p2p traffic on a separate ISP connection, just as you would choose a separate connection for http traffic? I tried all sorts of setups based on: http://www.braindump.dk/en/wiki/?wikipage=PolicyRouting but with no luck. Please help :) (ipp2p is up and running) _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl
