Has anyone set up pplotter to work with look n stop firewall.
i allowed ALL ICMP types under internet filtering tab and it worked. this is probably not the safest way to do it though.....

You need to allow ICMP Echo Requests outgoing and both ICMP Echo Replies and ICMP TTL Expired returning packets. We don't have this router anywhere inhouse, so I can't offer you much advice on how to configure it.

The good news is that most ICMP is relatively safe (some bugs in routers have allows ICMP to be exploited, but most of those bugs are no longer outstanding). A lot of routers block ICMP more for reasons of discovery rather than safety.

thanks for reply, look n stop has a free 30 day version. also well rated:

this is not a endorsement for look n stop, iam still trying to configure it the safest way, to work with ping plotter. thanks
