Hi,

L2TP tunnel is mjtually exclusive than IPSEC tunnel, Though the VPDN commands in "sh run" come after ISAKMP commands .

You cannot associate L2TP with crypto maps, crypto maps are only used for IPSEC tunnels. but if there are already existing VPDN commands for a tunnel, then you can add more VPDN commands, if you want.

pls update for further queries

Hi Aashish,

I've heeded your advice & configured the 2nd vpdn parameters.

My question is that once the client authenticates using username Hanuman & password how does the pix know which dialer pool to associate this user with.

I've attached a copy of both vpdn group configs.Group L2TP-VPDN-GROUP was previously configured & works.

Group L2TP-VPDN-GROUP-BCX is the new group.

vpdn group L2TP-VPDN-GROUP accept dialin l2tp

vpdn group L2TP-VPDN-GROUP ppp authentication chap

vpdn group L2TP-VPDN-GROUP client configuration address local CISCO

vpdn group L2TP-VPDN-GROUP client authentication local

vpdn group L2TP-VPDN-GROUP l2tp tunnel hello 60

vpdn group L2TP-VPDN-GROUP-BCX accept dialin l2tp

vpdn group L2TP-VPDN-GROUP-BCX ppp authentication chap

vpdn group L2TP-VPDN-GROUP-BCX client configuration address local Mataj1

vpdn group L2TP-VPDN-GROUP-BCX client authentication local

vpdn group L2TP-VPDN-GROUP-BCX l2tp tunnel hello 60

vpdn username Mother password ********

vpdn username Hanuman password *******

vpdn enable outside

I appreciate your assistance ...

Hi,

as the user will authenticate himself with "Hanuman" , as it is listed under VPDN group L2TP-VPDN-GROUP-BCX so "Mataj1" pool will be used. not the "CISCO" pool.

pls update for any other query

Hi,

this is exactly the question we are asking ourselves. How does the pix know which username is associated to which pool.

The vpdn username when created does not allow one to associate it with an ip pool ...
