You need the 'shared' option as well as 'track'. If you specify USE_DEFAULT_RT=Yes (which I recommend), then you need nothing in the COPY column. There are a couple of errors in the second line above; the provider name should be r2 and the gateway address should be 192.168.254.3. > > ip route add 10.0.0.0/8 via 192.168.254.1 table r1 > > ip route add 10.0.0.0/8 via 192.168.254.3 table r2 > > >>>>/etc/shorewall/routes #PROVIDER DEST GATEWAY DEVICE r1 10.0.0.0/8 192.168.254.1 eth0 r2 10.0.0.0/8 192.168.254.3 eth0 Those are superfluous, however, since the default routes for r1 and r2 go to the same gateways. > > -A PREROUTING -p tcp -m tcp --dport 22120 -j MARK --set-mark 0x01 > > -A PREROUTING -p tcp -m tcp --dport 22122 -j MARK --set-mark 0x02 > > >>>>|/etc/shorewall/tcrules| > >>>>>#ACTION SOURCE DEST PROTO PORT(S) >>>>>SOURCE USER TEST LENGTH TOS CONNBYTES HELPER > >>>>># >>>>> PORT(S) > >>>>>1:T 0.0.0.0/0 0.0.0.0/0 TCP 22120 >>>>>- - - - - - > >>>>>2:T 0.0.0.0/0 0.0.0.0/0 TCP 22122 #ACTION SOURCE DEST PROTO PORT(S) 1:P eth3 - tcp 22120 2:P eth3 - tcp 22122 There, I'm assuming that eth3 is the 'net' interface. >-A PREROUTING -p tcp -m tcp --dport 22120 -j DNAT --to-destination >10.0.2.62:6001 >-A PREROUTING -p tcp -m tcp --dport 22122 -j DNAT --to-destination >10.0.0.5:6001 >>>>>#ACTION SOURCE DEST PROTO DEST >>>>>SOURCE ORIGINAL > >>>>># >>>>> PORT PORT(S) DEST > >>>>>DNAT net apn:10.0.2.61:6001 tcp 22120 >>>>> - 196.44.33.33 > >>>>>DNAT net apn:10.0.0.5:6001 tcp 22122 >>>>> - 196.44.33.33 Those look correct, assuming that the server's net IP address is 196.44.33.33. > -A POSTROUTING -d 10.0.0.0/8 -j SNAT --to-source 192.168.254.2 > > >>>>|/etc/shorewall/masq| > > |>>>>|#INTERFACE SOURCE ADDRESS > PROTO PORT(S) > >>>>>eth0 ?? 192.168.254.2 #INTERFACE SOURCE ADDRESS eth0:10.0.0.0/8 - 192.168.254.2 -Tom -- Tom Eastep \ When I die, I want to go like my Grandfather who Shoreline, \ died peacefully in his sleep.
