OK here's a challenge. How to permit IP and ICMP Pings from a list of 40 subnets in an ACL.Should be straightforward? I thought so until I tried and realised the resulting ACL would be (40*8)+(40*7)=600 lines long!For each network I need the following (sorry about the lack fo formatting, presently neither IE or Chrome will persuade the forum to accept linefeeds or an attachment!!!)entry name {description "xxx" if { source-address x.x.x.x/x; protocol icmp; icmp-type 8; } then {permit;}}entry name {description "xxx" if { source-address x.x.x.x/x; protocol ip; } then {permit;}}Surely I must be wrong?

Not really, the thing is that's only the main part, there is still more where port/protocol check are needed so the whole ACL expands to over 800 lines when really there are only 100 lines in there that actually do anything - the rest is just pointless fluff around each actual ACE (from David_Rickard)

Can you agregate some subnets  ?
For example x.x.x.x/24 and y.y.y.y/24 to z.z.z.z/23 ?
