IP-Sec VPN not working anymore after firmware upgrade
I've been using this router for several weeks having configured several IP-Sec VPNs and they were all running well. Several VPNs were done with other Netgear Routers and also Sophos UTM. After upgra...
Hi DaneA
Sorry for my late reply as i have been sick lately.
Well Netgear sent me a new device. I installed all stored VPN settings and they are working fine. Then i did the firmware upgrade as well and the VPNs are still working.
So i think there must have been a hardware problem. I sent the other device back and probably Netgear will investigate the problem.
So they made me really happy as a customer and for sure i will remain a customer.
Thanks again to all you you involved to resolve may problems

Hi Sergek,
Welcome to the community! :)
Kindly answer the questions below:
a. Have you tried to delete the IKE and VPN policies then re-create it via the VPN Wizard after upgrading the firmware?
b. Did you factory reset the FVS336Gv3 after doing a firmware upgrade?

Hi DaneA
Yes i did delete all Policies and reconfigured them completely new. I did not use the wizzard to configure the VPNs but did all manually.
I also did the factory reset and put my saved configs o the router, this did not work either.
Now i am able to reconnect a VPN with aonther Netgear device such as the FVS336GV2 but it still does not work with my Sophos UTM9
Thanks for your help

It seems you have isolated the problem. Since you got the VPN tunnel established between the FVS336Gv2 and FVS336Gv3 then it means that got the configuration right on both VPN firewall routers. You might need to check the VPN configuration on the Sophos UTM.

So you suggest me to check all my other devices like the Sophos firewall, the Linksys routers, the Fritzboxes and all other connected devices ? How can it be that i had a system running for weeks and after a firmware upgrade nothing is working anymore .
Although i did not change any configuration on any of those other devices, no one except the Netgear to Netgear VPN is working anymore ? And even this VPN is not stable and i have to restart it daily.
If i change the V3 router with a V2 router using the same parameters, all works fine.
It seems to me that there is an issue with the new firmware since all other devices on my network are still fine, even the FVS336GV1 an 2 versions.
I had a similar issue two years ago when i made a firmware upgrade on my FVS336gv2. At least a firmware downgrade resolved the problem. But on my FVS336GV3 neither a Firmware downgrade nor anything else has resolved the problem so far.

I understand that its kinda odd that the VPN would suddenly not work after doing a firmware upgrade on the FVS336Gv3. I believe it would help if you could also check the device on the other end of the VPN setup which I believe is the Sophos firewall. Kindly check if the SA Lifetime matches as well as the IKE/VPN policies as well.
