Ok, this might just be a configuration with the initial Factory FW. They seem disabled by default so just re-enabling them should resolve this issue if using the initial FW version. Makes me wonder why they disabled them.

If anyone is experiencing issues like this, make sure all 4 Application Layer Gateway options are ENABLED. Even before updating FW.

Glad the beta is working as well. I would call this resolved. Hope it keeps working well for you.

Enjoy.

Sent you a PM.

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

Working for him, still not working for me. hahaha

I've tried the beta firmware, and all ALGs are enabled.

I would get hold of UGAW and see if maybe he can help you out on teamviewer and maybe review your router settings. I would also try a different router and a new modem and see. The 5 Series modems are ok however are low end. I recommend a SB 6121 if your ISP supports it. I would ask your IT group who handles the VPN for you if there is any specific needs for there VPN to work on routers. Most don't need any sort of configuration. I know my roommate doesn't need any and is handled at the client and host side of his VPN.

Keep us posted.

Sorry to bring up an old topic but I have been PM'd a couple of times about this to reply with my experience since.

Did you ever fix it?
I don't know if I ever did.  I just found a work around so I could avoid using a VPN.  My only advice would be to try flashing a couple different firmwares, try the latest first and work your way back. Maybe it's fixed.

Otherwise we may have had faulty routers or the VPN you are using is using an incompatible setting with the DIR-645.

Good luck.

Ok...thanks for sharing. Glad you found an alternate work around. I'll have D-Link review this as I see there is another person having some VPN issues.

[FurryNutz]

Can you provide us with some client VPN server information if possible? What brand or kind of VPN you were trying to use or connect too? This would be very helpful in D-Links review of this issue.

Please let us know.

Celsius,

I had the same problem with VPN via DIR-645. Eventually I solved it for my problem:
in Advanced > Firewall settings > (ALG) Configuration
all 4 settings were selected
when I unchecked IPSec (VPN) (other 3 still on)
my problem was solved

this is also mentioned in the online help:
IPSec (VPN)
Allows multiple VPN clients to connect to their corporate networks using IPSec. Some VPN clients support traversal of IPSec through NAT. This option may interfere with the operation of such VPN clients. If you are having trouble connecting with your corporate network, try disabling this option.

Maybe you can try this to
