Chris,
I have setup the 600k NTL cable modem via a RP114 router. It allows 4 machine out at once and it was so simple to set up. Just plug in the router connect all 4 machines and set each machine to obtain an IP address from NTL's DHCP range. I bought my router from Insight for about £55. They have since dropped to £50.99 and this includes 2 free NIC's.
I have only had one problem in 2 months and that was related to a power spike. I forgot to backup the config of the router and it lost all its settings as a result. 5 minutes later after I worked out what had happened I was back in business.
Also I have Cisco remote access to my office and this still works fine. It just sits in the tray and I wait for 'that call'
.
Hope this helps
Darren

I'm on NTL's cable modem service (640K one) - very good - great performance etc..
I'm looking at ways to link up a few PC's at home and share the line. Now I know I could do this by turning my W2K PC into a DHCP server and allocating addresses etc, but I was wondering if anyone had achieved the same thing by attaching a cable router (Linksys BEFSR41 for instance) via the Ethernet port of the cable modem and using the router to hide the PCs behind it using NAT?
The only reason I'm looking to do this is so that I can hook up my work laptop using an IPSec session back to the office and the company should pick up the cost of any new equipment needed.
Any thoughts or comments appreciated.

Yes can be done.
Connect the WAN side of the router to the cable modem, then plug
your PCs into the LAN side. The router acts as a DHCP server, allocating IPs to the PCs Dynamically and uses NAT to deliver the goods.
I used a Netgear Router with built in Wireless Access Point and connected two desktop PCs via CAT5 cable and my laptop using a wireless LAN card.
Most Cable Modems now accept at least 2 MAC addresses and you just need to cycle the power to the CM after switching to the router, but you may need to unplug the CM from the mains and the NTL cable for a few hours so that it forgets the MAC address of the currently connected PC and accepts that of the router instead.
Under NTLs acceptable use policy, you are permitted to connect up to 3 PCs.
Don't know about your IPSec requirements, but presume this can be done too.

That's my setup. I have NTL cable modem to Linksys BEFSR41, then 2 PC's, my XBox and Playstation hooked up. NTL have provided me with a hub for the XBox trial so at the weekend I'll be trying Cable Modem to Hub to Xbox and Router then from the Router to my PC's. Aparently I have two IP address's due to the Xbox Trial.

Thanks guys - couldn't see any reason why it wouldn't work - just nice to check if anyone else had done the same thing.
As regards IPSec - I know this will work as I have another session setup with a Cisco VPN client for accessing a customer's network.
Cheers

Correction to what Darlodge says, you set the PCs to get their IP addresses automatically, but it is the router - not NTL that issues them.
I've gone for static IP addressing, as I have port forwarding set up for one machine and wanted to ensure that this machine always had the same IP address.

Its a 2 stage transaction. The WAN side of the router gets its IP address from NTL. The LAN side of the router acts as DHCP server, allocating IPs to the PCs (usually in the range 192.168.0.x) and providing the NAT translation.
As you say, it works, which is the main thing

I think that hosting a VPN is against NTL's T & C's. I don't think that being a client of a VPN is against any rules. I might be wrong though

Well, I've got an Actiontec wireless cable router connected to my NTL line. Got two PCs hooked off the ethernet, and my laptop via the wireless connection. Works a treat.
I also use it to vpn into work from time to time, and have had no problems...
