This is, I think, a rather complex network/TCP issue. If anyone is thoroughly familiar with the workings of the tcp/ip 'rp_filter' setting, this might be a question for you. I am slowly beginning to migrate a test environment from openSUSE 11.0 to openSUSE 13.[12] (xen). In the PREV setting, I am running kernel 2.6.25.5-1.1-pae (on real iron), in the NEXT setting I am running 3.16.7-7-xen (virtual). In the PREV setting, I have the following: # cat /proc/sys/net/ipv4/conf/*/rp_filter 1 0 0 0 0 0 0 0 I.e. /proc/sys/net/ipv4/conf/all/rp_filter = 1. In the NEXT setting, I started with the same, but this prevented normal operation. Instead I had to change to: /proc/sys/net/ipv4/conf/ipip0/rp_filter = 2 /proc/sys/net/ipv4/conf/ipip1/rp_filter = 2 I'll be happy to explain the details of network setup (involves lvs, ipip tunnels and some masquerading). -- Per Jessen, Zürich (1.4°C) http://www.hostsuisse.com/ - virtual servers, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
