I'm trying to establish a l2tp connection between two microsoft boxes.
I have a cisco 2821 with ios 12.3 Can anyone point me in the right direction for a guide or tutorial?
Currently I'm using an access list to translate the traffic something like:
ip nat pool l2tp_serv 10.10.10.201 10.10.10.201 netmask 255.255.255.0
ip nat inside source list 190 pool l2tp_serv
10 permit esp any any
20 permit ahp any any
30 pemmit udp any eq isakmp any eq isakmp
40 pemit udp any eq non500-isakmp any eq non500-iskmp
admitedly, I don't understand nat well enough, much less l2tp/IPsec. It would be much easier if my company would just purchase a easy vpn device or something along those lines. However for now, I work with what I have :)
I also have a access-list for any connections outbound overloaded on the outside interface, so any traffic outbound should have no problems.
