IPOffice SCN via two firewalls

IPOffice SCN via two firewalls

IPOffice SCN via two firewalls

(OP)
Hi All

I have two IPOffice 500's i need to join with SCN. Each IPOffice sits behind a Sophos xg firewall and there is a Sophos "RED" link between the 2 firewalls.

The route from one IPOffice to the other via the 2 firewalls is wide open, no ports blocked as it is inside a private network.

I cannot get the SCN to connect. it does not matter how i set the NAT on the firewalls.

Anyone have any ideas how to get this to work please?

RE: IPOffice SCN via two firewalls

Do you have a VPN between the 2 firewalls or are you trying to connect the IPO's to the public addresses of the firewalls?

you must have a VPN
Also We had one cust who tried to use software VPN solution that used PPTP that they simply could not get to work - installing Daytek routers @ each end with ip-sec VPN between them proved the issue was with the customers VPN solution.
the exact cause was never identified (cust stuck with the Drayteks smile )

Hi IPGuru

The RED link is a Sophos proprietary vpn between the firewalls.

I am pretty sure that RED is neither pptp or ipsec

RE: IPOffice SCN via two firewalls

seems it doesn't work so use ipsec and it will work.
not much sense in troubleshooting if you can circumvent easier.

Which one is it, NAT or routed?
There shouldn't be any NAT, especially if you use H.323 SCN link.

Hi Janni78

Have tried with no Nat at all, no joy

RE: IPOffice SCN via two firewalls

After what I can tell by looking around a bit a RED link is always "NATed".

I am trying an IPSec vpn now.

Hi All

Thanks for the help.

I created an IPSec vpn and all is working.

RE: IPOffice SCN via two firewalls

If they are within a private network why can't you just create a direct link between the two XG firewalls? No need for VPN...

I worked with a customer who had branches connected through sophos red boxes. IPO and IPBS could be reached from the main side so I think it must not be necessarily NAT.
