Cisco 6xx DSL Router, ADSL, PPTP

[thirdfey]

Hey all,

The DSL router in our Maryland office needs to be replaced because it can not pass PPTP packets through it so their office cannot access our main network. I was told the Flowpointe router can let L2TP through but right now Microsoft's ISA Server does not work too well with L2TP. I want to check to see if there are possible firmware upgrades for the router which may allow PPTP passthrough and I can't get ahold of anyone in the Maryland office to ask them the specific model number.

I was thinking of using a Cisco 600 Series ADSL Router but need to know if I can set it up like a Linksys Cable/DSL router which uses from what Cisco tells me PAT and allow PPTP packets to pass through it. Anyone familiar with these routers? I saw Steve Porter posted some stuff on the 675 back a couple months. I cannot find it on Cisco's site spelled out the the router allows PPTP packets through it.

Thanks in advance,
Tony

I don't really know anything about what your talking about. But I have a cisco 678 if I can help you in any way.

thirdfey:
- what router do you actually have?
- is it right, that it doesn't do PAT/NAT?
- have you tried to forward the pptp-ports through it?

Okay, it is a Flowpoint 2210 but I think I have a cheap solution worked out for it. The Flowpoint is not our router, it is owned by the company that provides DSL to our MD office so I do not have any access to the router config. I don't think I am going to need the Cisco router now but if I do a guy I work with is good friends with a CCIE that works for Cisco so I think I am set with any questions I have about Cisco products Back to the Flowpoint router, it supports NAT but does not support PPTP passthrough. I hope that the latest version of its OS does, I believe 3.6.1. Oh well, I'll find out if this all works or not around Friday since my company doesn't move fast when I am on vacation. Thanks for the responses, I'll keep "y'all" up to date with what happens.

Have you read this?
http://support.efficient.com/kb/NAT/PPTP_with_NAT.htm

it describes how to set up a config for PPTP with the 2200 - certainly you'll have to have admin-rights!

Also read
http://support.efficient.com/kb/tech...P_with_NAT.htm for a short summary
and http://support.efficient.com/kb/FP/filterconcepts.html for a longer one (there's a pptp-chapter in it

Just read another hint:
"How do I get PPTP to work with NAT?
The router software must be above 2.5.2 ... "


damn... just saw that you mentioned a 2210 and not a 2200... didn't found if that should work with it (sorry man)!

if you want to dismiss the router it's worth a try
