FVS336Gv3 Weird Problem - VPN stuck and possibly blocking DMZ + DHCP on Port 4 ?
Hi I wonder if anyone has come across this. Just replaced a UTM-25 with a FVS336G v3 with firmware version: 4.3.4-2 which has been perfectly stable for about a month or so. Came to work this morni...
Hi
Thanks for the suggestion. Unfortunately, I went down this route with the UTM-25 and don't really have the luxury of continued disruption in the office doing the same with this new FWR so I've managed to get an RMA on the unit and have reverted back to the UTM-25 for the time being.
I've seen posts elsewhere on the net suggesting the clock skew issue was related to faulty PSU bricks. I guess only the tech guys who look at the returned unit will know. Hopefully there will be a new firmware release soon. It seems odd that it was perfectly stable for several weeks then seems to have thrown a complete "wobbler" in recent days. It resides on a surge protected UPS and the other equipment in the rack is fine
If the new unit fails the same way I'll have to look at an alternative product
Regards

We had a a serious problem in our domain which I now know is caused by the Netgear FWR deciding to act as an internal DHCP server. This has been a nightmare. Random round the site users losing authentication via a domain controller whilst working and, on investigation suddenly aren't connected to our Active Directory DC DHCP but have been assigned a high range IP of say .251 or .253 by the FWR even though it has not been set up to do so. The ipconfig also showed the network as company.com instead of company.local (the DC)
Rebooting the FVS unit after yesterday's issue with VPN blocking VLAN4 DHCP and then rebooting the workstation resolved the issue. Users can now connect to the A/D domain and resources if they reboot and log in again.
I think I will have to raise an RMA on this unit. It has worked fine for a month or two and I thought I had finally resolved the endless crash/reboot cycles with the older UTM-25 unit we had, only to find the FWR goes AWOL after a few weeks of use. Not a happy bunny :(
Ran out of time to edit 2nd post as I was interrupted to do some work ....
*Edit*
A few minutes after the last reboot the VPN link uptime shows 541686032.0 seconds with 3296 packets exchangedand the VPN dead. Again, no control over the VPN connection and I must have got lucky yesterday because disabling and re-enabling the current VPN policy has not revived the VPN link. After grabbing screendumps and because I don't have time to spend all day wiping and reconfiguring I'm going to fail the unit out. Also, DHCP working on DMZ/port4 but no ip based traffic passing through although DNS seems to work (ping 8.8.8.8 fails) from our DMZ/WLAN
