We have a Netscreen 5GT (ADSL) model.
We are trialling an Asterisk IP PBX and I was told to forward the ports UDP 5060-5061 and 10,000 to 20,000 to the PBX.
We have one static external IP, lets call it A.B.C.D.
Our PBX is at 192.168.1.175
Following instructions in this fourum and elsewhere, I've gone to the admin GUI and created a new service.
Next I went to network > interfaces > and then edit adsl1
then VIP > press "new VIP service"
This was where I hit trouble: I understand that the virtual ip field has my outside ip that is assigned automatically by my ISP, and this should be filled in automatically. it wasn't, instead 0.0.0.0 was thwere
when I typed my external IP in, and tried to Add, I got a msg saying :
"The virtual IP is the same as the address of the interface. Please set a different IP or select the <Same as the untrusted interface IP address> instead"
so I selected the <Same as the untrusted interface IP address> button, and tried to Add, but I got:
"Error: cannot add Untrust-IP VIP (A.B.C.D)"
..where a.b.c.d is our external IP
..so we can't proceed to create the new VIP service
what am i doing wrong here, or is there some way round this
ps I am not particularly techhie, and would prefer to do this via the GUI, if given the choice between gui and scripting config files...
