Hi Iain,
Glad to hear it worked for you.
Blocking traffic:
The reason for “Block If No Further Match” in filter rule 1 is that it blocks all traffic if there is no further match from a second or third filter.
The second filter (filter rule 2) contains the IP addresses of your SIP provider and therefore it give the match, so traffic over port 5060 can pass through only for these IP-addresses. All other addresses will be blocked.
IP range:
If the IP addresses given from your SIP provider are sequential, then is it possible to place them in one string, e.g. start address is x.x.x.134, end address is x.x.x.138
Click the “Edit” button behind “Source IP” then select “Range Address” and fill in the SIP provider “Start” and “End IP Address”
The field next to “Source IP” should be like “xx.xx.xx.134~xx.xx.xx.138”
I hope you understand what I mean. English is not my native language.
The manual Page 94 and further explained the settings of the Filter Setup. Maybe this will be more clearly to you.
Regards.
