[sr-dev] RTPengine iptables chain case sensitive?

[Peter Villeneuve]

Hi,

I compiled and installed deb packages as per the sipwise guide here
https://github.com/sipwise/rtpengine. After running modprobe xt_MEDIAPROXY
and iptables -I INPUT -p udp -j MEDIAPROXY --id 0 the new chain created is
mediaproxy (lower case). Isn't iptables case sensitive?
I'm not sure that it is working properly since it seems the mediaproxy
chain (lowercase) sends all UDP packets through the MEDIAPROXY (uppercase)
chain, which apparently didn't get created.

How can I check to make sure that indeed RTPengine is relaying the streams
properly?

Thanks


Here's what my iptables looks like after running modprobe
xt_MEDIAPROXY and iptables
-I INPUT -p udp -j MEDIAPROXY --id 0
