Maybe this also applies to the problem I have been fighting for the last several weeks. I have a VPN situation that requires a Linux router/firewall to route packets back out the same interface on which they came in. Julian, I saw this quote in the website you mentioned: By default, the Linux kernels drop packets with local source address from the forward path as "source martians". This is not controlled from the rp_filter flags. The following patches try to relax this rule and to allow the LVS director to be used as (default) gateway from real servers that send packets with VIP source, i.e. when the same IP is configured on the LVS director. What does this mean? Is this quote telling me that Linux kernels drop packets when their routes to the next hop go out the same interface on which they came in? thanks - Greg Scott -----Original Message----- From: Julian Anastasov [mailto:ja@xxxxxx] Sent: Monday, November 26, 2001 12:51 PM To: Whit Blauvelt Cc: LARTC@xxxxxxxxxxxxxxx Subject: Re: [LARTC] RTNETLINK answers: File exists Hello, On Mon, 26 Nov 2001, Whit Blauvelt wrote: > default via 66.95.83.209 dev eth1 > > # ip route add default via 65.84.205.97 dev eth2 > RTNETLINK answers: File exists It seems you are trying to use alternative routes. Use "ip route append" instead. You can also look at the following URL where the alt routes are extended: http://www.linuxvirtualserver.org/~julian/ look for "Static, Alternative Routes, Dead Gateway Detection, NAT" and also in dgd-usage.txt > Thanks, > Whit Regards -- Julian Anastasov <ja@xxxxxx> _______________________________________________ LARTC mailing list / LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://ds9a.nl/2.4Routing/
