Re: Cannot connect to static IP computer
Are you saying remotely that you cannot ping the static IPs? Can you ping the gateway?
Of the five static IP's, one is solid and good, another is sporadic and the remaining three are pretty much unreachable. I have screen shots of pingplotter which I can post. Could the issue be that the network cards or wiring is a problem? Should I get those tested?
If you are able to ping one of the IPs or the gateway IP then it wouldn't be CV. It could either be physical issues if you're either losing connectivity from one of the computers in question or experiencing packet loss or latency), but more likely there's some sort of firewall or ACL that is not permitting responses to pings. These machines have static IPs I'm assuming?
When you mention being unable to connect to them, is that also a remote connection to them, or unable to connect online when you use them?
Yes I have 5 static IPs. I am trying to connect via remote desktop connection. But I am testing each of the IP's, one is solid, one is mostly unavailable and three cannot be contacted at all.
Have you tried to connect to the computers from within your office LAN? If you can get to one, then I can't think of anything that would stop you from getting to the others.
Are all computers connected directly to the CV router?
NOTHING justifies terrorism. We don't negotiate with terrorists. Those that support terrorists are terrorists.
The Cisco 851 is only a 4 port router, so there needs to be at least one switch or router connected.
CV doesn't block RDP, and you can say with 100% certainty that the request is approved through the modem & 851 since it works for one. If the ones not working all connect through the same router or switch, and the other is not (or connected with a DMZ through the router), you can find a common point of failure. If they are through separate routers/firewalls, I'd suggest checking the firewall on the computer when you try to connect, if possible, then check any router connected one step closer to the internet until you see it being rejected.
