I have 2910 and behind router I have Asterisk. I'm receiving attacks and I would like to block some IP address but I can't do that.
In Firewall/Filter Setup I added filter (block WAN-LAN from IP address) rule but traffic is still arriving to asterisk. What I'm doing wrong?
Also I tried the same thing but with different address (for test). I blocked IP for accessing WEB server and this was doing well. Why this was OK I don't know. Probably TCP/IP filtering is OK and when I try to filter UDP then it doesn't work.

Any solutions?

Thanx,
