FortiClient VPN - Connects ok, BUT No Remote Access & No Internet
I have a remote user that for an unknown reason started to have issues connecting remotely.
No changes were done on the Fortigate. According to the user not no changes on the remote user side network (same ISP, same router). Previous to the issue they had been connecting without any issues since it was setup months ago on a daily basis.
FortiClient connects but I lose Internet access and I cant ping the devices at the main office. I also noticed that I dont get an IP assigned.
I already restarted the Fortigate and deleted and recreated the FortiClient VPN.
Office/Fortigate network/subnet is 10.10.10.0
Remote sites network/subnet is 10.0.0.0
I have experience issues in the past with overlapping subnets with FortiClient, but in those cases the device connecting remotely didnt loose Internet access, it just had issues accessing some devices at the office if some IP overlapped. They have been working fine for months
Could it be issues with the subnets? Something else?
