Hi,

I have very very simple config, yet can not get it working.

Situation:

VE0 (host):
eth0 Link encap:Ethernet HWaddr 00:30:05:E3:85:FF

VE 10 needs to get following network data:
IP: 85.31.187.53
Broadcast: 85.31.187.255
Netmask: 255.255.254.0
Gateway: 85.31.187.1

I have tried simple venet and also veth, but I can not get it working Sad

With venet, once logged into VE I can go outside (internet), I can also ping VE from VE0 (host), but I can not reach it from internet Sad

Please help!? Smile

Thanx
Aleks

For crying out loud...

I am almost there Smile

Now, all works: except HN firewall (iptables) is blocking my VE to do DNS resolving.

Meaning, from VE:

[root@www /]# ping www.google.com
ping: unknown host www.google.com

If I stop iptables on HN, then it works Sad

I scooped through forum, tried many different solutions, yet it is not working Sad

Please - HELP! Smile

Thanx,
Aleks

Hi,

You can reach your VE from internet with running firewall on your HN and with downing iptables you can DNS resolving, can't you?

Please, check, that the packets following from/to VE are not drop by firewall and DNS server is set on VE.

1. Can you ping www.google.com using it IP address if firewall on your HN is on?
2. Please, type this command into VE and show the result:
"cat /etc/resolv.conf"
3. Can you show the result of "iptables -t filter -L" command on HN?
4. Also "iptables -t nat -L" (on HN)?

Hi,

I have disabled iptables on HN. It has further no services running on it as I will be running all from VPS itself.

Now it works all ok. I just had no time, nor nerves to bother with IP forwarding Smile

Aleks
