Re: Connecting two private networks over the internet

Make 
sure you port forward ALL the relevent ports in the routers to the GnuGK box 
behind the router.

UDP 
1719 (done)
TCP 
1721 (done)
TCP 
30000 - 32000
UDP 
50000 - 60000

This 
should now work.

Subject:  
  Connecting two private networks over the internet

  Hello, 

  I am trying to place 
  calls between two separate private networks, each using it's own 
  GnuGk as a gatekeeper, over the internet. Each private network is 
  behind a firewall. I have each GnuGK's Neighbor set up as the opposite 
  router's public IP address. Port forwarding is enabled for 1719 and 1721.

  Each phone on the 
  two networks registers with his GnuGK using a local E.164 alias. 
  Outgoing calls are then placed using the remote E.164 
  alias.

  Can anyone help me configure 
  both GnuGk's correctly ?  Thank you.
