Juniper SRX1800 LAC

[chieftan]

This is what I though would be a simple question, but it appears that no one can help and I cannot find it documented anywhere with Juniper (Surprise)....

I am configuring a new ISP consisting of all Juniper kit as follows:

MX240 - PE/LNS
MX240 - PE/LNS
MX240 Core - JVC
MX240 Core - JVC
SRX1800
SRX1800

Now the topology would include the PE ---> CE...

I have completed the following successfully:

IPv6/IPv4 Dual Stacked
IS-IS as the IGP
MPLS and RSVP (to the PE only)

Now is where I need help or direction:

The PE will also act as an LNS (L2TP Network Server).... however, before this can be put into a test production environment, it first needs to be tested in house and for that I need a LAC (L2TP Access Concentrator).

Question: Can I utilise the SRX1800 as a LAC?

Here's hoping
