Hello David

Thank you for this excellent idea of allowing more and more CCIE candidates to use your , I can say that now, excellent product. As you probably remember  I thought of using it for a long time but this promotion has given me the opportunity to do it .

I have Dynamips there and there is no better combination of the 2 together while doing configurations.

Best regards

Thanks for the answer, it's been getting to me for months, and I just keep forgetting to ask you for a solution. You have no idea how much time that little command is going to safe me. I'm working on a huge security network which has over 80 firewalls some of which have over 3000 lines of access-lists.

It's a pain in the neck trying to find a single host with a certain port to see if the access-list exists, so this is going to safe me a stack of time :)
