Port Forwarding issue in the XG 210 Firmware SFOS 17.1.1 MR-1

I will try to understand your request.

You have "multiple devices" (VOIP Phones?) behind a XG and want to forward some certain ports to those devices? 

First of all : Telnet only works for TCP. But this should not be an issue here.

Second: You should be take a look into your requirements, because this is not quite possible to do like you explain. 

You have one IP as WAN. So basically you can port forward for example 5060 UDP to one Device behind XG. But not to all devices because XG does not know how to decide which phone should get connected. 

At this point we are in the SIP protocol. Check out the SIP KBA:

And the explanation of SIP: https://en.wikipedia.org/wiki/Session_Initiation_Protocol

after this 

admin console in the sophos we had written this command in the console.

system system_modules sip unload

System system_modules sip load

after this ?

we have only one Panasonic vc devices they said open this port 

1. 5060tcp udp both, 5100-5135udp, 5200-5235udp, 1719udp, 1720tcp – to open this port

how can i do this.

Hi,

you have to do a DNAT.

hi, this blocking from the Local ISP.

now it is solved. 

ok thank you for such  time.

we already configured DNAT in the firewall giving plan rule in firewall.
