[asterisk-users] Proxying from one server to another

[Adrian Marsh]

Hi David,

 

Thanks for the reply. That's pretty much what I've already tried, but
with no luck on the production machines.  In testing it worked, but the
public IPs and single NICs were causing issues (we believe)

So I was looking for a proxy-type solution.

 

Adrian

Redirect traffic with iptables like this:

 

Host ~# iptables -t nat -I PREROUTING -d OLD_PUBLIC_IP -j DNAT --to
NEW_PUBLIC_IP

 

I'm not sure if this will work for SIP. You may need the proxy to change
info in the sip messages between server and client.

Hi All,

 

I'm trying to find a software package to do the following sip proxy
work:

 

I've an A*k server A that needs to be decommissioned, from the USA, and
replaced by server B, in the UK. Both servers are on public internet
IPs.

Whilst the client migration happens, I want to divert all the Register
traffic from Server A to Server B to catch any clients still left out
there.

 

Unfortunately, the original Clients were configured with static IPs
instead of DNS names for the SIP Registrar, so I have to proxy Server A
until all the clients have been updated (which might be a long time).

 

Obviously A*k itself wont do this (as far as I know).  I've looked at
siproxyd and party-sip, but with no success so far.

I've also tried using IPtables to redirect at the IP level, but the
public IP ranges seem to stop me from achieving this. It works in my
local-lan testing, but not on the public servers.

 

Any ideas?

 

Thanks,

 

Adrian
