Currently, I have 2 Linksys BEFXS41 Routers at two locations talking to each other via VPN, and that is working fine. But, ever since I installed that, replacing an older Linksys BEFSR11 Router, users have been getting knocked off our HP3000 server about once a day. One person suggested that I install a router in front of the HP3000 to insolate it from all the network traffic that doesn’t involve it. The HP is an older computer and he thinks that all the Internet-related traffic is overwhelming it. The network IP addresses are 192.168.1.X with a mask of 255.255.255.0.
How would I setup the router on the HP3000 so that everyone on our network (and site 2) would still have access to it? Do I need to go to a mask of 255.255.0.0 in order to make sure that the HP3000 can get to the rest of the network (including printers at site 1 and 2) and everyone can Telnet to the HP3000 (including site 2)?
I was going to try using the Linksys BEFSR11 that I still have as the router, but I noticed that it requires the mask to be 255.255.255.x. Seems like when I was playing around with it, I could get to the main network, but I was invisible to everyone on the main network. Do I need a more expensive router that will give me more flexibility with the mask? Do I need to change the whole network IP addressing that I use?
