Hi. The task: 1. There 3 servers and a router with 2 PPPoE connections (let call them: ppp0, ppp1). 2. There are several groups of Inet-clients to be served (Servers, Clients and Club). 3. The task is: - to route Club through the ppp1; - to Servers and Clients through ppp0; (Next is reproduced from memory and may be slightly incorrect) router # netstat -nr Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 a1.a2.a3.a4 0.0.0.0 255.255.255.255 U 0 0 0 ppp0 b1.b2.b3.b4 0.0.0.0 255.255.255.255 U 0 0 0 ppp1 router # cat /etc/iproute2/rt_tables # # reserved values # 255 local 254 main 253 default 0 unspec # # local # #1 inr.ruhep 200 Servers 201 Clients 202 Club router # ip rule ls 0: from all lookup local 32763: from 10.10.100.101/24 lookup Club 32764: from 10.10.100.100/24 lookup Clients 32765: from 192.168.1.0/24 lookup Servers 32766: from all lookup main 32767: from all lookup default router # ip route ls table Clients default via a1.a2.a3.a4 dev ppp0 router # ip route ls table Servers default via a1.a2.a3.a4 dev ppp0 router # ip route ls table Club default via b1.b2.b3.b4 dev ppp1 ======================================== So, to summarize, the is no default route in main routing table. Each group of clients is to be routed through its respective connection, and, when its connection is down it is not to be routed. This scheme works almost fine, 10.10.100.100/24 addresses are really being routed through ppp0, 10.10.100.101/24 through ppp1 and 192.168.1.0/24 (3 Servers) through ppp0. BUT the router itself (192.168.1.4) has no route to any host. I get "network is unreachable" to any connectiion attempt from 192.168.1.4. And I can't connect to this router from outside, because the packets have no route to be sent back. I thought that there is different routing politics for localhost and added default route to "local" table. 192.168.1.4 has started to have the route, but the rest of the scheme started to work incorrectly. So, the question is: how does the routing of packets comming from localhost is being accomplished? As to me there is a kind of "vicious circle" situation, because to enter alternative routing table there should already be "source address", but for localhost which have many source addresses it should decide which route it needs to have the corresponding "source address" be set. -- Покотиленко Костик <casper@xxxxxxxxxxxx> _______________________________________________ LARTC mailing list LARTC@xxxxxxxxxxxxxxx http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
