ICMP Firewall Test

Can anyone suggest a free online firewall tool that performs various ICMP tests?

I'm already aware of GRC and AuditMyPC - I need something more advanced.

Thanks!

 

Ummm not sure if this is what you are looking for.
It is not online but no install is required (1 file).

 

i redzero, i suggest you load nmap on another computer in your network (if available) and play with that, its got a nice user interface where you can specifiy mostly everything in regards to network testing.

nmap can't scan itself on windows xp sp2 though! but if you're on older os than that, you can scan yourself. (but that might bypass the firewall since you're local, depends on your setup)
