After changing a VLAN ... SSL VPN traffic is no more working

[tobi_m]

Hi all,

since i changed 2 internal vlan on a FortiGate 90G .... SSL is no more working.

SSL VPN is connecting, but no traffic is going throw. 

Does anyone have an idea? the firewall policy and also paket capture are not seing any Packets.

Hello Tobi,

It looks like a policy issue. Please check if you have a firewall policy to allow to this vlan. Also if you are using split tunnel please verify on your SSL VPN portal if there is any other routing address added then you will need to add this new vlan's subnet as well.

Hi, if i disable split tunneling. SSL VPN is Connecting and after like 2 seconds it is closing. So its no more working then.

If its active like it was before. its connecting but not working...
