Help needed... kind of newbie :)

hello,

I have to sites with Fortigate 80c 5.2.3

the site to site is working great but..

On the first Site there is a PBX win the address 172.30.0.X that's connected to the DMZ leg with dhcp relay to the internal network which is 192.168.1.X and and sitting on VLAN number 2.

when i plug an ip phone and tell him is on vlan number 2 everything is working fine - he gets his address and we can use the phone.

i need to find a way to configure the other site to be able to connect to the PBX so we can put extension there.

i can't get from the remote site to the pbx,

is there any way to accomplish that?

i need the vlan recognized and the ip phone to be able to connect to the PBX and to get an ip-address from the dhcp server.

any step by step from you guys?

thanks in advanced
