Ok.
Only other thing you could do is call up SHAW and ask them if they see any issues on there end regarding this and note the time frames. I don't think there is any big issue on there end however doesn't hurt. Maybe they can watch there logs and verify anything while you trying the VPN.

Other than this, i'm running out of ideas. I would try a different router for sure.
Only other think you could try is to take the router to a friend, neighbor or families house and test if you can go mobile with laptop. I presume the issue might track. Thats kind of extreme but helps to narrow down things.

If I hear back from my sources I'll let you know.

Let us know what you decide to do.

It's been 4 days, and all the old problems are still happening.
I called Shaw, and they said it's on my end and their system is functioning the same way, and working properly.

I tried our old router and it works with VPN finally, it's just this new DIR-645.

I guess my option now is to return it and get a new one, unless there is anything else.

Oh, I also go my network admin at work to restart the core network and the VPN server, no luck.

Couple of items to review if you want:

Let us know if this works or not.
It's possible that the 645 doesn't handle VPN like it should or there is a problem with it.

Now sure what you want me to do based on that thread, I don't see anything for me to do.

Just solved my VPN connection problem, just thought I'd pass along.

Couldn't get my Cisco VPN client to connect at all.

Went into Advanced > Firewall Settings and enabled all four of the following:
PPTP : 
IPSec (VPN) : 
RTSP : 
SIP

Viola. Works now. Time will tell how stable the connection is.

[FurryNutz]

Kewl. I didnt know they were disabled. Usually they are enables by default on othere router. Glad it works for you. Enjoy.

[Celcius]

I tried that, still no luck for me.

[FurryNutz]

Maybe stocktiki can help offer some more details of how he got his working. I would make contact with him.

Hi all,

Thanks god I'm not alone with this problem! I'm getting crazy. VPN connection can be established successfuly with AGL IPSEC enabled. Without IPSEC enabled I can't connect to VPN (which I can understand)

Followed by a successful connection initialization I get a time out and VPN disconnects. Sometimes after seconds, sometimes after minutes.

I am experiencing exactly the same as described in this post. Already tried every setting on the router. Even DMZ (client) does not work.
With another router everything is working fine. Problem must come from the router itself and not from the ISP, Modem or VPN client.

Here the VPN details of the company I work for.

---------------

Work with your ISP (internet service provider) to verify and ensure the ports below are open:

Packet filters for Point-to-Point Tunneling Protocol (PPTP)
TCP destination port of 1723   = PPTP tunnel maintenance traffic
IP Protocol ID of 47    = PPTP tunneled data
Packet filters for Layer Two Tunneling Protocol over Internet Protocol security (L2TP/IPSec)
UDP destination port of 500   = Internet Key Exchange (IKE) traffic
UDP destination port of 1701   = allows L2TP traffic
UDP destination port of 4500   = IPSec network address translator traversal (NAT-T) traffic

---------------

Anyone an idea? Maybe because of the mix of protocols?
I really love this router except from the VPN problem...

Cheers

What ISP Service do you have? Cable or DSL?
What ISP Modem do you have? Stand Alone or built in router?
What ISP Modem make and model do you have?
If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems.
To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.

Some things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

It's working now with the Beta firmware!

I have a DSL. Modem is set as bridge. I think this was only a firmware problem.

can someone confirm? anyone else experiencing/experienced the same?

[FurryNutz]

What version of FW did you load? Where did you get the Beta from? FTP?

[ugaw]

I loaded the beta from the FTP
ftp.dlink.com/Gateway/dir645/Beta/Firmware/DIR645A1_FW102B08_BETA.zip

VPN is now working with just IPSEC enabled in ALG. No port forwarding etc!

[FurryNutz]

Is all 4 of the Firewall options ON by default after loading new FW? I'm curious if they are disabled now by default.

[ugaw]

hm I don't know because it used the old configs.
But with factory firmware all 4 options were disabled by default!
