Dear ukrm VPN , D-Link DSL504 and Nildram

Again, I'm looking for help.

I've got Nildram broadband installed and I've worked out why I want
broadband; it's so I can work from home.

So I've got a nice little ADSL Router (D-Link DSL504) which is meant to
support VPN (or at least pass through for VPN). Nothing in its config
about enabling VPN.

So, connected laptop to router, switch it on. DHCP does it stuff and
I've got connectivity to the internet; looking good.

Open the VPN dialer and... it doesn't work. Says "remote peer is no
longer responding"; it does this after it's contacted the first gateway
at on IP address and started the "balancing" bit.

Plugged in my GPRS card and it works as per normal.

Tried another laptop; same response.


Bit of a pisser really.

So, what's up? Don't Nildram support VPN? Or is it the router I'm
using?

Anyone got any ideas?

 

Same router, different ISP and it works fine here. No settings needed on
DSL504 it's all done on the laptop software.

Have you told work about which ISP you are using? I had to tell mine to
ensure the VPN would work.

No, not done that. Might be worth a try.

Thanks for your help.

I VPN to my work network and I use Nildram as my ISP. So you can cross
Nildram off your list of things causing the problem. Curiously I use a
D-Link router as well (DSL-604+) and don't have any problems (and I didn't
need to configure anything for VPN over the router either). I would be more
inclined to believe that it's your router causing the problem, as I had
similar symptoms as you describe with a different router.

HTH

 

Im on nildram, and use VPN to break the servers remotely
Using a Netopia Caymen though.

does the router have a firewall and is it blocking vpn or is vpn passthrough
turned on.
The caymen is good in that it does both pass through and router termination
for vpn.

 

I spoke to D-Link and they talked me through it. Basically I had to
enable DMZ and open up the IP address allocated to my laptop.

Not sure this is the best way because surely I only need *some* of the
ports open for VPN?

 

Which VPN client software is it?

Anyway, I see by your posts here that "working from home" is going
well

 

My crowd have rebranded it but I believe it's Cisco.

 

*cough* well I did two hours fucking about last night. And it's only a
couple of minutes.

Anyhow I generally put in 50-60 hours a week so having a day or so where
I do 7 hours doesn't make me feel bad.

OK.

Default ports for the Cisco VPN v2.5.2 and v3.0 client with 'IPSEC
through NAT' enabled are UDP 500 (IPSEC), 10000 (ESP header) allowed to
originate from either the client or the VPN concentrator.

However, true IPSEC doesn't used TCP ports 50 or 51 but "protocol 50"
and "protocol 51". (TCP itself is protocol 6). If your version of the
client doesn't support an 'IPSEC Through NAT' option you're probably
stuck with forwarding everything as you do now.

HTH.

 

That's odd because I altered nothing at all. Certainly didn't need DMZ.
However I do have to make sure the laptop gets a new IP (DHCP from the
D-Link unit) as it tends to keep leases for 24 hours and it thinks it's
still at work.

Different client or summat. Still all working now and I've added a
wireless access point to the setup this evening so I can work all around
the house... and probably the garden too.

 

What did you get then?

 

Just a D-Link thing, DWL-2000AP. It's just the WAP bit- 802.11G.

Works well enough and was up and running within around 2 mins of
connecting it to my ADSL Router.

Pity it's not colour co-ordinated though...
