Paul, > Have a look at the Fedora examples at http://www.shorewall.net/bridge.html > (about halfway down the page) for ifcfg-br0 and ifcfg-eth* OK, I have put the FC scripts in place as ifcfg-eth[012] and ifcfg-br0, and put the script as /etc/rc.d/init.d/network The system seems to come up sane and working internally. However, it cannot 'ping' out, or be 'ping'ed in by another machine on the LAN. Both say 'no route to host' ifconfig now says: br0 Link encap:Ethernet HWaddr 00:00:00:00:00:00 inet addr:192.168.1.64 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::200:ff:fe00:0/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:27 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:1302 (1.2 Kb) eth0 Link encap:Ethernet HWaddr 00:50:22:20:2F:67 inet6 addr: fe80::250:22ff:fe20:2f67/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:45 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:5 dropped:0 overruns:0 carrier:10 collisions:0 txqueuelen:1000 RX bytes:4493 (4.3 Kb) TX bytes:0 (0.0 b) Interrupt:11 Base address:0x8c00 eth1 Link encap:Ethernet HWaddr 00:50:22:20:22:03 inet6 addr: fe80::250:22ff:fe20:2203/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:426 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:5 dropped:0 overruns:0 carrier:10 collisions:0 txqueuelen:1000 RX bytes:29611 (28.9 Kb) TX bytes:0 (0.0 b) Interrupt:10 Base address:0xa000 eth2 Link encap:Ethernet HWaddr 00:50:22:28:04:59 inet6 addr: fe80::250:22ff:fe28:459/64 Scope:Link UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:48 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:5 dropped:0 overruns:0 carrier:10 collisions:0 txqueuelen:1000 RX bytes:6055 (5.9 Kb) TX bytes:0 (0.0 b) Interrupt:5 Base address:0xfc00 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:1847 errors:0 dropped:0 overruns:0 frame:0 TX packets:1847 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:1821804 (1.7 Mb) TX bytes:1821804 (1.7 Mb) I set the bridge IP address to 192.168.1.64, with a netmask of 255.255.255.0 The other machine on the LAN is at 192.168.1.10 route says: Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 * 255.255.255.0 U 0 0 0 br0 It seems so close, but something is still missing - any ideas ?
