Hi Carsten,
I would say maybe the requests are not sent from the proper interfaces(
Ex: sending from the public interface requests to the local proxies).
Please check this with tcpump.
when you have multiple interface, there are two options:
- do the interface selection manually via the force_send_socket()
- let the kernel to choose the appropriate interface based on the
destination address. For this you need to enable the proxy option
mhomed. See
http://openser.org/dokuwiki/doku.php?id=openser_core_cookbook#mhomed

Hi Everybody,
I have some problems with a System which has several network
interfaces and multiple network interfaces. The system basically
receives requests on the public socket/ip and sends them, via the
private socket to some proxies, which "do the work". It's a kind of
load-balancer based on OpenSER 1.0.1 and the Dispatcher Module from
1.1 / CVS.
Everything works fine, but sometimes i see some ICMP Messages
(Destination not reachable / Port not reachable) on this
"loadbalancer"; as a response to requests from the Proxies to the
loadbalancer. Has anybody seen this issue before? Any ideas, what's
wrong? Any known issues? Are there any known problems with multiple
interfaces? Any known issues with more than one processor? I've copied
my configuration below, any thing in capital letters are Parameters
from my M4 file...
The system is not really on high load, has 64 children and should
easily handle the load... (Dual Intel [EMAIL PROTECTED], 1 Gig of Ram)
Any help would be appreciated...
Thanks in advance,
Carsten
