how to config interface port for DDNS to work with SSL VPN ?

[akabarasif]

hi,

i have a fiber link from ISP which is connected to router or modem provided by ISP. from that 1 link is directly connected to firewall with an ip 172.x.x.x. when i select the interface in SSL VPN config i get 172.x.x.x IP. how can i config interface so ddns can work with sslvpn.

i have contacted support and he said you need to config 0.0.0.0/0.0.0.0 but it doesn't work because from modem private IP is config. i cannot connect directly because its fiber link and our firewall 101F doesn't have fiber port.

kindly assist.

Have you configured a port forward from the ISP router public ip and desired port to your fortigate Wan private IP and port?
