Public IP setup with AT&T and WatchGuard XTM
Posted on 2011-02-17
Ok Experts, I'm calling on you in my most desparate time. I have a situation that is complicated, and there is a lot to read, I will try to keep it clear.
I am currently at one of my field offices setting up the network and connecting the BOVPN. I am running into problems getting everything synced up. Here are the key players:
AT&T DSL Service with 5 Static IPs
WatchGuard XTM 22 router/firewall
Here are the logistics:
AT&T DSL was installed with a Motorola Netopia 3347-02 Modem/Router
My IP Block is as follows:
Public IP 99.x.x.169 to 99.x.x.173 (Usable)
Default Gateway is 99.x.x.174
Subnet Mask is 255.x.x.248
The modem was configured with a PPPoE of email@example.com
The WatchGuard XTM 22 is configured using a Static IP of 99.x.x.169/29 and Gateway of 99.x.x.174
Ok, so I have tried to set the Motorola Netopia to Bridge mode, basically disabling all of its settings, except for the modem portion. The WAN IP interface has been configured to use the PPPoE settings. From what I can see, the modem tells me it is bridge mode.
When I have the Watchguard box external interface to the 99.x.x.169, my network has no internet access. If I set the external interface to PPPoE using the supplid info, and using either "obtain IP" or setting the IP to the 99.x.x.169, my network has internet access, but my XTM 22 reads it's IP as 99.x.x.174 and has a completely different subnet mask and default gateway.
I also cannot ping the 99.x.x.169 or 99.x.x.174 or any of my other Static IPs. However, when I have the XTM set to use the PPPoE settings, and I set a laptop to the 99.x.x.169 credentials, I have internet access, and I can ping that IP from the outsite, however, I am at that point connecting to the modem, and not my XTM.
I have made 5 calls into AT&T, ranging from Home Tier 1 to Business Tier 1, and all they canm say is that their equipment is working. I am at a loss, I am asking for anyone who has experience dealing with AT&T DSL for thier business network to help me out on this. I have gone through all the settings pages for the modem, and it just won't work the way it should.
So if anyone out there can give me some pointers on where to look on this particular modem, or has dealt with this mess before and knows what needs to be done, you'll be a life saver!! If you need more info, please don't hesitate to ask!!!
