Hello all Maybe it is only complicated for me, maybe someone knows how to do it better? I would like to make redundant path between host in the Internet (I will call it ExternalDataServer), and host in my Lan (InternalDataServer) ExternalDataServer Router (iproute2) 12.34.56.67 (only one IP) <---> 22.33.44.55 eth0 <---> 33.44.55.66 ppp0 44.55.66.1 eth1 <- --> InternalDataServer 44.55.66.77 Route to InternalDataServer is fixed, I cannot changed it. It is described in routing table of my ISP. I tried to specify src addres as src of router, and then use NAT to translate adress coming from 12.34.56.67 to router as 44.55.66.77 (forward everything to this addres) Does it make sense, could it work? I will appreciacte any advice Thx Michal Bialecki
