      Do you get the same IP on vpn as you do when not on vpn?

        @viragomann I do see some Blocks on the Firewall logs but I dont have pfBlockerNG or squid packages installed.

        Which type of VPN is it? I am using a Forticlient applicatiion

        Are there any blocks in the firewall log shown up? I was seeing a lot of blocked ipv6 so allowed ipv6 through but still the same issue.

        one of the weird things is that a packet capture doesnt show me anything as well.

            Did this VPN work behind another router?

                What do the firewall logs show for the client when its connected to the fortclient VPN.
                Do you see any blocks? All flows are getting passed?
                For my Global Connect client (Palo Alto) on my work laptop the only rules it has is to the internet - permit any/any. Works without issue when sitting behind my pfsense.

                  All the webiste and protocol's works fine.
                  I can access the internet without a problem, even now as we speak i am going through the FW.

                  Its just the forticlient that doesnt connect.

                        These log seem to be from different devices.

                        Did you any mess with the outbound NAT on pfSense?

                          @phoenixfsense Im not really seeing a problem. The 192.168.0.102 device connected fine.
                          Your 192.168.88.10 seems to have trouble.
                          Thats on a separate VLAN? If so does that any the same access rules as 192.168.0.102

                          This is why i asked you to review the firewall rules. Something is clearly different here in your setup.

                            Ok Its the same device- the reason why you see two defirent IP address is because I have to bypass the Pfsense or use a mobile router.

                            Outbound NAT : Mode Automatic

                              I expect that the IPSec client use port 4500 for NAT traversal.
                              So I'm wondering, why the not working log shows port 500, but the working shows 4500.

                                Just curious but if you do a WAN side packet capture do you see packets going to your companys vpn gateway?
                                If so there is something they are seeing and not liking.
                                Unfortunately the logs on the client arent very verbose.

                                  If that is the case then it would mean that the issue is on the pfsense.
                                  This is easy to believe because both my 5G and Mobile LTE are on the same provider.

                                    @phoenixfsense I know it's been a while but I'm experiencing the same issue. I was wondering if you were ever able to resolve the issue and what you did? Thanks.
