Need Setup Help for Home/Work Network w/Cable Modem

glojeans
I have a cable connection. My work sent me a AT&T NetGate 8100 VPN router. It connects my work PC and an IP phone and is secured & my home network will not run off of it. I am currently disconnecting the modem from my work setup and plugging into my home network when I am not working, but my IP phone loses its program and it takes forever to get the work connection back up again.
Is there a way I can connect BOTH the work VPN router setup and my home Cisco Linksys wired/wireless network so I don't have to unplug/plug them back & forth? I don't need to access the Internet at the same time for work & home, but need to leave the work computer/IP phone plugged in for updates, etc.
If you have a solution, could you please explain in simple terms, I am not a very advanced networker.
Thank you.

Then what you need is a double point phone connector that fits into your normal phone socket, have a look at this picture so that you know what i am on about: http://www.gogocost.com/xcart/product.php?productid=162

You just plug this into your phone socket and then plug your two phone cables relating to your two routers and you are done.
Cheaper too.

No, does not connect by phone, it is a cable connection w/cable TV. The cable modem only has one Cat 5 cable connection for a router.

What kind of connection(s) is connected to your router?
What kind of connection to the internet do you have? (IE, satellite, normal phone line etc etc)
Basically, the more info you give, the more help you receive. :)

I have cable broadband connection with a cable modem. I need to connect a work related VPN secure router that connects my work computer and VOIP phone (VPN router does not let me pass a connection thru to my home router) and also connect my home wireless/wired router to connect my desktop and wireless laptop. I need to leave the work VPN router connected at all times for updates. I tried using a switch, but that did not seem to work. Had the switch connected to the modem, then the VPN router on one port and my wireless on another. VPN router worked thru the switch, but my home wireless did not.

info needed to configure it?

there's no reason why you can have your router directly connected to your cable internet server and then connect your vpn router to your router and put that connection on a DMZ port.

This should allow you both internet and a vpn connect to your work. That VPN router should not monopolize your cable internet service.

I have:
1. Cable modem.
2. Home router (Cisco/Lynsys Wireless/Wired)
3. Work router (VPN secure AT&T Gateway configured by employer)
4. Linksys/Cisco 10/11 5 port workgroup switch

I tried going from the cable modem to my home router then from a wired port on my home router to the work VPN router, doesn't work. I tried cable modem to switch then to both routers; doesn't work either.
Does anyone have any other configs that might work or do I have to do something to my home router to make it work??
Thanks for any assistance.

note: If the VPN gateway appliance provided by your employer is preconfigured, then they must have given you an information packet on how to set it up.

With that information packet, they would have told you what VPN protocols they are using, what ports need to be open etc.

What your home router needs to do is forward the VPN traffic to the company supplied appliance. Note: if the company supplied appliance is a "gateway" eg router, you probably will have to ship it back and have them configure it to work on your network with your router eg WAN port static address and subnet mask, DNS servers corresponding to your home router subnet and then configure the LAN on the company supplied appliance to be a different subnet than your home LAN.

Note: if the VPN is a point to point VPN, you probably will have to setup their appliance on a DMZ zone. If not then you need to forward VPN traffic to the appliance by directing PPTP, L2TP IPSec traffic to it.

Also note: only computers behind the VPN appliance will be able to access the VPN tunnel and probably not have Internet access via the VPN tunnel.

So you'll have to swap cables around when you want to use the company VPN.

I recall from a past exercise similar to this, my cable provider instructed me to connect a hub and not a switch. There is a difference to the cable modem. In that way your VPN applicane and your router can both get an IP address from your ISP. Obviously you would need to confirm this with your provider.
Otherwise (as indicated in another response) add the necesary logical port numbers on your router to direct traffic inwards to the VPN appliance. You would then add necessary static routes on yuor PC to point to the VPN appliance as the next hop tp encryptde networks and the existing router would remain the default gateway.
