Proxy and a single NIC? CatchAll

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Scenario:
======

I have an ADSL line with a dynamic public IP and a dyndns address for it.

I have my gnugk running on a single NIC with an internal IP address 192.168.1.15

I have my gnugk in the DMZ of the ADSL router and have done port forwarding to it.

I have my endpoints registered and calling between them.

T_120 	Always On 	tcp 	1503 - 1503 	1503 - 1503 	192.168.1.15 	
	
H_323 	Always On 	tcp/udp 	1718 - 1721 	1718 - 1721 	192.168.1.15 		
H245_Q931 	Always On 	tcp 	30000 - 32000 	30000 - 32000 	192.168.1.15 		
RTP 	Always On 	udp 	1024 - 60200 	1024 - 60200 	192.168.1.15 		



Problem 1:
=======

The moment I add the lines below for external calls, a few of my endpoints suddenly cannot register and get the messages below that:
ExternalIP=mydomain.co.za
ExternalIsDynamic=1

2009/10/27 11:09:06.644 2 RasSrv.cxx(175) RAS Read from 192.168.1.70:1719 2009/10/27 11:09:06.645 2 RasSrv.cxx(226) RAS Received GRQ from 192.168.1.70:1719 2009/10/27 11:09:06.645 1 RasSrv.cxx(354) RAS GRQ Received from 192.168.1.70:1719 2009/10/27 11:09:06.646 2 RasSrv.cxx(394) GCF|192.168.1.70|5678|terminal; 2009/10/27 11:09:06.646 2 RasSrv.cxx(238) RAS Send GCF to 192.168.1.70:1719

The systems that fail after I add the lines are Aethra Maia XC and Aethra Vega X3 running version 1.5.23 and 12.1.10 software respectively.

Q> Does this mean that in Proxy mode the gatekeeper needs two NICs, one facing the external network and one facing the internal private side?

I assume this will cure the endpoints failing to register.

Problem 2:
=======

I am using Polycom PVX internally and can do calls to an external IP just fine, but external systems cannot call into my internal endpoints.

Here is my config:

[Gatekeeper::Main]
Fourtytwo=42
TimeToLive=60
ExternalIP=mydomain.co.za
ExternalIsDynamic=1
DefaultDomain=mydomain.co.za

[RoutedMode]
GKRouted=0
H245Routed=0
AcceptUnregisteredCalls=1
Q931PortRange=30000-30999
H245PortRange=31000-31999

[Proxy]
Enable=1
ProxyAlways=1
InternalNetwork=192.168.1.0/16
T120PortRange=50000-59999
RTPPortRange=1024-65535
ProxyForNAT=1

[GkStatus::Auth]
rule=allow

[RoutingPolicy]
default=explicit,internal,dns,catchall

[Routing::CatchAll]
CatchAllAlias=1234

[RasSrv::LRQFeatures]
AcceptNonNeighborLRQ=1

[RasSrv::RRQFeatures]
SupportDynamicIP=1


The moment I enable GkRouted or H245Routed in [RoutedMode] nothing works.

Do I need to modify my CName DNS records to point to my extensions like so:

1234@      points to    mydomain.co.za

At the moment if I call from an external unregistered public IP to any of my extensions I get a "No route to destination" message.

Once this is all working:
===============

I assume that external unregistered callers will be able to call to any of the internal extensions by using extension@xxxxxxxxxxxxxxx

I'd also like to send all incomming calls to mydomain.co.za to a specific extension specified in the CatchAllAllias setting to create a receptionist effect.


I have been battling this one for a week now. Any help or guidance will be rewarded.
