 Posted: Sat Oct 06, 2012 6:42 pm Post subject: [SOLVED]Access Static IP from gentoo xen domU |
 |
|
Hi all,
I'm trying to set up my domU to have access to my public static IPs provided by my ISP. I've followed the Gentoo Home Router Guide to configure the dnsmasq and iptables and the other computers on my network are working just fine, but since then my other 3 gentoo xen domU can not get an address the way they usually did.
Here goes my configuration
/etc/conf.d/net
| Code: |
dns_servers="XXX.XX.XX.2 XXX.XX.XX.3"
config_eth1="10.0.0.101 broadcast 10.0.0.255 netmask 255.255.255.0"
bridge_xenbr0="eth0"
config_xenbr0="XXX.XX.XXX.170 broadcast XXX.XX.XXX.175 netmask 255.255.255.248"
routes_xenbr0="default gw XXX.XX.XXX.169"
|
/etc/dnsmasq.conf
| Code: |
interface=eth1
dhcp-range=10.0.0.100,10.0.0.250,72h
|
/sbin/iptables -L -v
| Code: | Chain INPUT (policy ACCEPT 15958 packets, 22M bytes)
pkts bytes target prot opt in out source destination
29 2248 ACCEPT all -- lo any anywhere anywhere
3979 350K ACCEPT all -- eth1 any anywhere anywhere
28 9388 REJECT udp -- !eth1 any anywhere anywhere udp dpt:bootps reject-with icmp-port-unreachable
0 0 REJECT udp -- !eth1 any anywhere anywhere udp dpt:domain reject-with icmp-port-unreachable
0 0 ACCEPT tcp -- xenbr0 any anywhere anywhere tcp dpt:ssh
8 408 DROP tcp -- !eth1 any anywhere anywhere tcp dpts:0:1023
0 0 DROP udp -- !eth1 any anywhere anywhere udp dpts:0:1023
Chain FORWARD (policy DROP 230 packets, 47574 bytes)
pkts bytes target prot opt in out source destination
0 0 DROP all -- eth1 any anywhere 10.0.0.0/16
22667 3379K ACCEPT all -- eth1 any 10.0.0.0/16 anywhere
25715 25M ACCEPT all -- xenbr0 any anywhere 10.0.0.0/16
Chain OUTPUT (policy ACCEPT 13485 packets, 1369K bytes)
pkts bytes target prot opt in out source destination

All my domU uses dhcp to fetch an address, which means they don't have any configuration on theirs /etc/conf.d/net. I'd like them to have public IPs What am I doing wrong? or What else should I do? Thanks

Ok,
By disabling netfilter on sysctl.conf as described [url=here]http://wiki.xen.org/wiki/Network_Configuration_Examples_(Xen_4.1%2B)[/url] my domU could get my static public IP. There's only one thing now, one particularly domU (The most important, where I host my application used by my entire company) must have a internal ip, which means it has to be in the 255.255.255.0 netmask. How can I achieve that now? |

Ok!
I solved my problem by creating two bridges! Now everything is working as it should!
