Pfsense 2.0.1 - WAN gets DHCP IP from ISP but clients have no internet access
miles267 last edited by
Recently I noticed I'm unable to connect to the internet or ping internet addresses from my pfsense box.
As a test, I've done a clean install of pfsense 2.0.1 to confirm that my NIC adapters are detected and there are no hardware issues. After assigning my em0-LAN and em1-WAN (DHCP), I was able to browse the web from a client PC without issue.
I then restored from a recent backup I had (9/24/12) but am unable to browse the internet after the restore. Each of my interfaces accurately reflect the MAC and IPs but I cannot ping an internet address from the pfsense box either.
Is there anything I can do to manually reset my WAN interface from a shell prompt? Within the webUI, any attempt to re-save the WAN and reboot the pfsense box fails to correct my issue. My pfsense box was working less than 2 days ago and suddenly no internet access. Am trying to avoid a complete clean install as I'm not sure I could easily re-configure each of my settings manually. It has taken me months to customize to my current settings.
Thanks in advance.

Posting the ping command you used and the first few lines of the response would be much more informative than "cannot ping".

It is not obvious that would fix the problem, but maybe there is something you haven't told us.
Please post the output of pfSense shell command```
Please post the output of pfSense shell commands``` # netstat -r -n # ifconfig # /etc/rc.banner ```so we can verify you have a sensible routing table.

I am also facing almost the same problem, using Pfsense 2.0 WAN is working in PPPoE mode and getting the live IP from ISP but internet is not working on Clint Computers, and i am unable to ping any website from WAN port. please help.

Everyone is going to need a bit more information. Some has already been asked for, so if you are going to post here and you see that someone has already posted, perhaps you could have gone ahead and run the commands listed before posting.
First thing is to try a reboot.
Then from a computer behind the FW run a traceroute to something like 184.108.40.206 and post it here.
If it doesn't make the round trip, try from the FW itself. Perhaps the modem is not in bridge mode.
Check some logs and post any errors.

then, assuming you are trying to ping from the pfsense box itself, you either have a routing problem of some sort or your ISP is blocking your connection requests, possibly because you have changed devices. It may be you have the wrong subnet mask. pfSense strictly adheres to the rules when it comes to talking to devices in a different subnet, other OSs do not (Windows). Hence it may be that your ISP is giving you IP information which worked fine with your previous router but is actually incorrect.
This is pure speculation. ;)
As Podilarius said please give us more information. Answering Wallabybob's questions above would be a good start.
