 Subject: Re: [OpenSIPS-Users] Mediaproxy receives only
 
  What could be a possible cause of mediaproxy (current src) to only  
  receive media from both parties but not to relay it.
 
 There are a number of possible causes:
 
 1. Check that there is no iptables rule blocking the traffic
 2. Make sure IP forwarding is enabled:
 /proc/sys/net/ipv4/ip_forward should be 1
 3. Make sure rp_filter is disabled:
 /proc/sys/net/ipv4/conf/all/rp_filter is 0
 /proc/sys/net/ipv4/conf/default/rp_filter is 0
 /proc/sys/net/ipv4/conf/eth0/rp_filter is 0 (replace eth0 with  
 whatever interface you use)

The rp_filter has been set to 1. I have overlooked this.

Thanks for the helpful hint!

Best regards
Sebastian

[OpenSIPS-Users] Mediaproxy receives only

[Schumann Sebastian]

Hi

What could be a possible cause of mediaproxy (current src) to only receive 
media from both parties but not to relay it.

This is dispatcher output:

This is the relay output:

Traffic goes from both clients to the mediaproxy, but the mediaproxy only sends 
one packet in the beginning to both clients and then not again...

Dispatcher is colocated with OpenSIPS and relay is on a separate machine.

Any further info needed?

Thanks!

Sebastian
