Topic: CLI warning error

[edeganay]

Hello,
I havn't been around for a while, but I have an interesting issue.
I just changed my sip provider to a new (cheaper) one.
Everything is (almost) fine, except a constant error message on the asterisk log and CLI
chan_sip.c:6797 determine_firstline_parts: Bad request protocol Packet

The SIP Provider knows it, ans propose a solution :
iptables -A INPUT -p udp -m udp --dport 5060 -m string --string "Cirpack KeepAlive Packet" --algo bm --to 65535 --source SIPProviderAddress -j DROP

I know that doing this will be done untill SME reboot, how to add this permanently ?

More over, when pasting the commande to SME commandline, I have the following error

iptables v1.2.11: Couldn't load match `string':/lib/iptables/libipt_string.so: cannot open shared object file: No such file or directory

Try `iptables -h' or 'iptables --help' for more information.



any idea to what to do ?

Hi

I think you should re-post this in the contribs section of the site because this is a firewall issue and nothing to do with SAIL.  There are SME experts on that forum who I'm sure can help you.   I might add that I've never before heard of a SIP provider requiring special firewall rules be applied.  If it were me, I think I might be tempted to choose a different provider.  Anyway... there is some information here

Hello,
1 year later, I did'nt find how to add patches.

Actually, I found this explanation :

but couldn't find the asterisk source in SME

Any help ?
Many thanks,
Edd
