Hello all,
There is a Suse 10 dom0 machine which is acting as a router. It has two
ethernet cards, one assinged a public address and the other a private one.
The machine also logins to a VPN server on the public network (via eth0) and
it can route traffic requests from one network to another. This is the
configuration:
eth0 Link encap:Ethernet HWaddr 00:30:05:AC:15:26
inet addr:xxxxxxx Bcast:xxxxxxxx Mask:255.255.252.0
inet6 addr: fe80::230:5ff:feac:1526/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
eth1 Link encap:Ethernet HWaddr 00:10:A7:16:AC:E6
inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0
inet6 addr: fe80::210:a7ff:fe16:ace6/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
ppp0 Link encap:Point-to-Point Protocol
inet addr:10.1.251.25 P-t-P:xxxxxxxx Mask:255.255.255.255
UP POINTOPOINT RUNNING NOARP MULTICAST MTU:1000 Metric:1
I use XEN with bridging on eth1 card and that results in that domUs have
adresses from 192.168.0.0 network. It all works fine, except that I cannot
access the 10.0.0.0/8 from 192.168.0.0/24 anymore. The following rules work
when XEN bridge is not enabled:
ip route add ''10.0.0.0/8'' dev ''ppp0''
iptables --insert OUTPUT 1 --source 0.0.0.0/0.0.0.0 --destination
10.0.0.0/8--jump ACCEPT --out-interface ''ppp0''
iptables --insert INPUT 1 --source 10.0.0.0/8 --destination
0.0.0.0/0.0.0.0--jump ACCEPT --in-interface ''ppp0''
iptables --insert FORWARD 1 --source 0.0.0.0/0.0.0.0 --destination
10.0.0.0/8 --jump ACCEPT --out-interface ''ppp0''
iptables --insert FORWARD 1 --source 10.0.0.0/8 --destination
0.0.0.0/0.0.0.0 --jump ACCEPT
iptables --table nat --append POSTROUTING --out-interface
''ppp0'' --jump
MASQUERADE
iptables --append FORWARD --protocol tcp --tcp-flags SYN,RST SYN --jump
TCPMSS --clamp-mss-to-pmtu
but they do no work when the packets come through the xen bridge. The
problem is that the packets that coming out from the ppp0 interface have
source ip 192.68.0.x rather than 10.1.251.25, the address of the ppp0
interface, ie masquerading does not work.
What rules should I have to so both networks, 10.0.0.0/8 and 192.168.0.0/24,
speak to each other? Do I have to use ebtables together with iptables or
not?
Thanks in advance!
Regards,
Thanasis
