Changing routers messed up my web server on my virtual PC

Question

I changed my router and now my virtual PC HTTP web server is not working. Any ideas?

I added the entry of this virtual PC to my virtual servers on my new router to be an HTTP server. Not sure what else I'm missing?

Maybe I need to clear cache or something? I can't even ping my virtual PC anymore.

I suspect that the new router has either:

a. renumbered your internal network's IP addresses; or,

b. doesn't have TCP port forwarding (or a DMZ) set up like the previous one did.

	a. it did renumber the internal network, but everything is dhcp b. on my new router it says Block ICMP ping (does that mean i can't ping my internal network) – Rod Mar 19 '11 at 4:14
	@rod: Usually it means that ICMP requests for "ping" from hosts on the public side will be ignored. You should still be able to use ping internally. – Randolf Richardson Mar 19 '11 at 4:42
	Just had to toggle my Windows FireWall on and off and it started working again. Is that strange? – Rod Mar 19 '11 at 5:11
	@rod: Yes and no. Unfortunately the Windows Firewall does interfere with a lot programs, and customizations is often required to make it work properly. The best approach to use is to create an exception for the specific application or TCP/UDP port numbers (and document what it's used for in the comments box that Windows provides when you do this). – Randolf Richardson Mar 19 '11 at 18:01
