Hello
I'm having an issue with Skype and call quality because of UDP blocking.
A forum/Google search did not turn up anything relevant.
Using ASG home licence 8.202 - (haven't updated in awhile)
In the Skype Call Technical Info window, I have consistently bad local UDP.
Skype Call Technical Info dialog
-------------------------------------------
Packet loss=0.0% (5)
Send packet loss=0.0%/0.0%
Recv packet loss=0.1%/0.1%
UDP status=local:Bad remote:Good
-------------------------------------------
From O'Reilly Skype Hacks: "If either end of a Skype call has poor UDP, call quality will suffer"
I use the SOCKS5 proxy /w authentication for Skype, and have no problems making/receiving calls.
I have an allow all firewall rule for the port I'm using for incoming connections.
and a DNAT rule: Allow - Any->Skype->WAN - Dest: MYPC - Auto Firewall rule
I tried turning off IPS or making an allow all for ICMP/UDP in IPS exceptions as a test - no good
Also tried turning of ICMP and UDP flood protection.
All tests with the Skype Echo Call Test Service consistently show bad local UDP,
in the Call Technical Info dialog.
IPS log shows
severity="info" sys="SecureNet" sub="ips" name="ICMP flood detected" action="ICMP flood" fwrule="60014" initf="eth0" srcip="MYPC" dstip="ASG"
Anyone have an idea what I can do about this?

Hi orangealert,
Did you find a solution for this?
We are using UTM 9 (9.411-3) and i have the same issue. Audio Quality is bad with breaks.
Did you have a working config now?
Thanks
Stephan
Hi,, Stephan, and welcome to the UTM Community!
What do you learn from doing #1 in Rulz?
Cheers - Bob
Hi Bob
Thanks, very good Post!
I have checked #1
- Firewall Log shows dropping udp 35xxx to 443 if i analyze the skype connection
- UDP Flood Protection is off
Checking also #3 - #5. Found some direct bindings.
I will check skype again tomorrow.
Cheers Stephan

yes..use the socks proxy and then in the settings of skype you have to tel it to use the proxy on the ASg...best way to do this and you don't have to go chasing all of hte p2p ports skype uses..[:)] I did this and skype works wonderfully.
I had the same problem with Skype and I have solved it with your recommendation. I was going crazy for several weeks... I just wanted to thank you for the help [Y]
