2WIRE need bridge for static lan ips


I have managed to get myself in ever tightening circles over this one.

Have a server running Mandriva 2007.1. Run our own dns because we run our own mail server as well as others. The system has 3 nic cards. Formerly, we relied on a D-Link router which cashed in its chips 2 weeks ago. My isp provider replaced it with a 2WIRE 2700HG-E. Firewalling suddenly became a problem. Previously, we had relied totally on shorewall to limit port access.

I know at the software level I have to introduce split-dns and make some adjustments in sendmail. That's okay.

My problem is the 2WIRE hookup.

I first set up the 3 nic cards for dhcp. 2WIRE shows the devices as being 'present' but at this point it is the luck of the draw as to which is labeled 'active'. That's understandable for the moment. Not much to choose between, after all.

Then I enabled the bridge network because I think that is what I need to do from all the colvoluted reading I've done on this.

But I need 2 of these devices to be reassigned to static ips for the benefit of the local dns and mx hosts. I just cannot get my head around how this is to be done.

Hopefully, there is someone out there who has passed this way before and can give me a pointer or two. I must add that the isp provider's version of 2WIRE does not include the mdc (diagnostic) console, which might have allowed me to help myself a bit more.

Thank's so much!

2Wire static IP setup

I recently received a 2Wire 2701 from my ISP and I'm attempting a similar setup.

So far I've been able to use the "Public Proxied Subnet" setting to pass 1 public IP to a pfSense firewall behind the 2Wire. I've attempted to assign another public IP to a separate interface (also on the pfSense), but it seems like the 2Wire identifies the host by using the hostname. As a result, it will not allow me to assign a separate IP for the second interface because the hostname is the same for both. Why the 2Wire does not rely on MAC addresses to identify the host is anyone's guess.

Anyway, still working on the problem and I'll post any progress here. Sounds like we need someone with more experience with the 2Wire gateways as I have none.

Looks like this problem is not going to be resolved. I have spent 2 weeks with it and I don't even want to think of the cost, let alone the frustration.

So .... I am off to buy a D-Link modem - which is what I had been using for the past 5 years. I'm content to let shorewall block ports which is all a firewall does anyway.

There is another thread running about a similar problem on this forum so it is certainly not an isolated one among those of us who run servers.

Well I've been hopefully watching too and it seems like you just might be right, I will relay this question to some guys that I think might have relevant expertise. Once again good luck!

You could try the following command as root:


lspci | grep net
dmesg | grep -i "net"
dmesg | grep -i "eth"
ip link show

Here follows a short summary of what these commands do.
show pci modules located, and search for "net"
show whether the kernel picked up a driver for these cards
show whether they have been assigned eth numbers
show the link status of ethernet devices

If you are haveing driver issues, you may want to lay your hands on realtec 8139 NICS
they are the most common, and unless i'm mistaken, the d-link cards also use the realtec 8139 modules
