Networks

If you have NAT going, the only way to access the other computers is to run PCAnywhere on each and have them wait as host.

You PCAnywhere into the NATted IP address, then from there you PCAnywhere into the second ip address. In other words, from the NATted computer you run PCAnywhere as host (yes, within the first), and connect to one of the other "remotes" setup on the machine with NAT.

Unfortunately, it's slow and clunky (you have a second PCanywhere screen within the first -- which limits the screen size and manipulations using scrollbars are difficult until you get used to it), but it does work and is a way around NAT.

First of all, most companies with 5 or more pc's usually use NAT or PAT. If the internal pc's need access to the Internet than you need a device to convert ethernet to T1 or DSL or ISDN. The Cisco 1700 router will run NAT and convert to T1. Another device that is used to conect ethernet to the internet is a CSU/DSU or cable modem. If your converter does not have IP filtering capabilities (firewall) you should buy an firewall appliance like a Sonicwall SOHO box) It can run NAT and protect your network. With NAT you now can connect hundreds of PC's using private addresses. That is, if your using NAT and want to connect to the internet your need to change all your pc's IP addresses to 10.x.x.x or 172.16.xx~172.31.255.255 or 192.168.x.x. Now to access your Network from home you could buy a LanRover box and dial in using a regular phone line. The Lanrover, if DHCP is set up, will automatically give you an Private address from a poll of addresses you setup that is in the range of all your other PC's at work. now you login and its like sitting at work. run your pcanywhere using an IP address and your screaming. Good luck.

derekhyps answer is pretty complete, but here are a few alternatives and specifics - Get an inexpensive combination router/firewall from Linksys or Netgear - these include NAT and the ability to forward incoming packets by port number to certain internal IP addresses. This is important for pcAnywhere and also if you have an internal email or web server of any kind. Your DSL or cable modem will connect directly to the Linksys router through a special port, and then you connect the router to the rest of your network by either uplinking it to your internal hub or switch, or by using the hub built into the router (some have only 4 ports so you need to be sure you get one with at least 8 ports if you're going to do that). Assuming you have a full-time Internet connection (DSL/Cable/T1), you can use pcAnywhere directly over the Internet. Set up your router to forward incoming packets to your PC(s) that are running pcAnywhere and waiting as a host(s). You need to configure the router, the pcAnywhere host software on the internal PC and the pcAnywhere remote software on the remote PC to use the same ports. If you want to connect to only one PC from outside, then you can use the default ports of 5631 and 5632. Then, from there, you can connect to other internal PCs as suggested by Anna, but you will have you learn how to negotiate the double-window effect (we do it all the time). However, if you need or want to connect to more than one PC from different remote PCs simultaneously, you have to manually configure additional ports in the pcAnywhere software. Here's an example:
