Hi, When u have aggressive mode u exchange messages with the ids in cleartext while performing dh, i believe that's the main reason why you don't have to have a dns server configured in order to make it work. If it was main mode it would not work because when the isakmp responder receives a

Hi Eugene, As far as I understand your quetion you are probably missunderstanding the use of port mapping for non-standard ports. Look, for mapping standard applications to non-standard ports gou can use ip-port map [application] port [non-standard port]. What u cannot do for this case is for

Hi Anthony. Mentioning ip virtual-reassembly as a part of CBAC/ZBF, did you actually test this as a standalone feature or did you always use it as a part of your CBAC/ZBF configuration? Cheers A. On 6/18/2012 12:22 PM, Anthony Sequeira wrote: Here is a post I did today on this topic.

Bruno, what you are saying is correct, in aggressive mode the IKE id is sent in clear text but I don't think that this answers my question. If you take a look at the config/debug output in my first post, the initiator router sends its hostname as the IKE ID but the receiving router doesn't

Hi Bruno, Haven’t we seen the debugs where the initiator sends its hostname as an ID not the IP address? The main question is how the responder knows the IP address of the initiator. Eugene From: ccie_security-boun...@onlinestudylist.com [mailto:ccie_security-boun...@onlinestudylist.com] On

Hi Eugene, Sorry, again, as other times I have put myself ahead of everything. When you configure your crypto map to apply in your interface you have to put the set peer command with the ip address, unless you have a DNS server configured for it to resolve the hostname. So again, there are 2

My $0.02 to what I have always thought about it. First, I'd stay away from stack-start l2-start if I know for sure that IP-TCP runs over ETHER and doesn't encapsulates it somehow differently, i.e. I'd start my stack type class-map with IP matching thus making router's life easier. But it's

Anthony, Thanks for your daily bit on the challenge. I am following it as I will also do my lab around the same time. I am under the impression that virtual-reassembly always has to be applied to the outside int when CBAC and ZBF is used. Is this correct? I am busy with a VII IPEXPERT
