Sar715pv Pptn

[redtitan]

I am trying to do this

XP AT HOME-->PPTP-->705-->INTERNET-->715PV-->OFFICE SUB-NET

I have bought a SAR715PV for my office because of the clever(?)
PPTP termination options. I am using a 705 at home (we are in process of kicking out ISDN). Both work well for Internet access!

My home XP has a PPTP connection which duly connects/registers and authenticates to one of the configured VPN on the 715 all the way through the Internet.

If I do an IPCONFIG on the XP I see my new IP address from the 715 PPTP pool

e.g.

IP.......195.72.138.52
Subnet mask .... 255.255.255.255
Default gateway...195.72.138.52

52 is an IP address on my office sub-net.
The 715 is IP 195.72.138.60 on the IPLAN side

THE PROBLEM IS I CANNOT SEE OR PING ANY OTHER IP ON THE OFFICE SUB-NET SO IT IS NOT MUCH USE REALLY.

What have I done wrong?

Why do I get the the "all bits on" sub-net mask dished out to me?

Why can't I get out of the 715PV?

Do I need RIP?

The 705 has NAT on and is transparent to GRE protocol and port 1723.

Help

Sorry that subject should read PPTP:confused:

Having never used that particular router for the endpoint of vpn I'm stabbing in the dark :)

Client side looks ok from that.

On the VPN server, is there a route that says something like 195.172.138.0, gateway = 195.72.138.60
Or possible an option to allow vpn clients access to local network.

BTW can you ping the routers local ipaddress ??

What I really need is a complete configuration dump for a known to work 715VP doing PPTP termination but it (at least the VP part) is a bit of new device in the UK.

Yes - I think the client must be OK or I would not be getting authenticated.

I do have an IP ROUTE on the office 715VP. I tried both a gateway=195.72.138.60 and the alternative INTERFACE=IPLAN styles.

There did not seem to be any option to let vpn clients access to the local network although I have not yet crawled completely through the CLI.

Sadly the logged in VPN client can only ping the allocated PC. It doesn't seem anything gets out of the 715. XP PPTP client reports increments in the bytes sent but nothing ever comes back.

Thanks for your comments anyway.

As far as PPTP or L2TP is concerned the only experience I have is doing a connection from simple dial up.

But....

As far as the router is concerned there are only two things to set:

A global IP pool for the incoming call (i.e. a list of IP addresses to be allocated to the callers). Please note the IP pools MUST be on a different range to the router/LAN network e.g. if router/LAN is 192.168.0.x then IP pool could, for example, be 192.168.1.x.

A list of users; username/passwords etc.... Initially, for testing. create a user with full rights.

Make sure that IPSec encryption is turned off as mentioned in the setup guide.

thanks steve -

Ahhh - my router is on the same IP sub-net as the PPTN pool. I will try this as soon as I get back to the office.

Steve,

To recap I am trying to

XP AT HOME-->PPTP-->705-->INTERNET-->715PV-->OFFICE SUB-NET

You suggested that the PPTP IP address pool should be on a different sub-net than the 715. I tried this and it still does not work.

My PPTP client on my XP tunnels all the way to the office network but I cannot see(PING or otherwise) any other adresses on the office network.

SOLWISE 715VPN IP is factory default 192.168 etc.,

The remote PC client gets the following configuration when dialing in

PPP adapter rt:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 195.72.138.52
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . : 195.72.138.52

This is what I would expect. 195.72.138.52 is an IP from the pool and is part of the office network.

In desparation I tried configuring the 715 to have an IP route to 195.72.138.0 but that didn't help either.

Can anybody confirm that this product has been seen acting as a PPTP endpoint.

Yes! We have PPTP working here and yesterday John had a PPTP link from the office to his house (SAR715 at the office and PV at home) and he was downloading files from his PC's at home.

Also Mr Saffron (ref ADSL guide) has got it working.
