Need help with PPTP pass through on Cisco 1604 [7:8332]

I was wondering if some one can help me with the NAT command to allow pptp to pass through my Cisco 1604. I thought this would get it: ip nat inside source static tcp x.x.x.x 1723 x.x.x.x 1723 where x is my IP scheme, but this does not seem to work for me. Any help is appreciated. Stephen

Does the DCN (640-441 for CCDA) test tell you how many answers to give on the multiple answer questions, or does it simply say "Choose all the apply"? Or is it a combination of the two? Thanks! Stephen Dallas, Texas ___ UPDATED Posting Guidelines: http://www.gro

Does MLS (Layer 3 switching) require VLANs? [7:63147]

routing info and then know to switch to that port? I am not seeing where the requirement for the VLAN comes into play. If VLANs are required for layer 3 switching, is that pretty much standard across the industry, or that a Cisco only thing? Thanks! Stephen Hoover Dallas, Texas Message Posted at

Re: Does MLS (Layer 3 switching) require VLANs? [7:63147]

derstand that inter-VLAN routing requires L3 switching - but is the opposite also true? Does L3 switching require VLANs to be defined? If that is the case, then it would lead me to believe that L3 switching is based on VLAN info and not on the IP address, but I don't think that is correct.

Re: Does MLS (Layer 3 switching) require VLANs? [7:63147]

. In my previous example, 2 hosts on the same L3 switch, but on 2 different IP subnets - wouldn't a defined Ethernet subinterface be each clients respective gateway, and thus normal L3 routing would occur, just at switch speeds Thanks again! Stephen Hoover Dallas, Texas Me
