I am reaching out for help here as I am beyond tired of dealing with working from home over the last 8 months with my DIR-655 wireless router.  Everything that connects wirelessly in my home connects and stays connected with no issues to the DIR-655.  The only thing that doesn't work is when I am connected on my laptop to work using a Cisco VPN Client (Version 4.6.03.0021).  I get connected but unfortunately I can never stay connected for more then a few minutes.  I need to remain connected all day but I have to keep re-establishing connection at random times throughout the day.  I get connected so I know the problem isn't on the work end and also I connect via VPN on my laptop all over the world when I travel and it never drops connection.  The only time this happens is at home with my DIR-655 router so I can only believe that there are some incorrect settings or something that causes my VPN connection to drop at random.

Anyone have any ideas?  

Here is the error log on the Cisco VPN Client itself:

ON THE DIR-655 - I consistently see ICMP packet (Type Three and Type Eight) outgoing and incoming requests being blocked.  Could these part of the issue?

You may try to disable SPI Firewall in the router menu and set
NAT Endoint Filtering: UDP: Endpoint Independent and TCP: Address Restricted

192.168.10.x is your homenetwork ?
Your user has administrative permissions ?

Also if you have different profiles in the client, try to choose a UDP profile: IPSec over UDP (NAT/PAT)
If you only have a IPSec over TCP profile to connect, please ask your administrators.
(But if there is only one connection, it should also work)

You are using Win XP I assume from the client version. If you have enabled windows firewall, disable it.

Do only one change at a time, so you will see whether it helps.

I'm using up to 5 Cisco client connections here (Version 5.0.05.0280) with Vista and Win7 without any disconnects. It worked with XP the same (we had a 4.8... version there).

I had the exact same issue.  My Cisco VPN connection would always die randomly on my dir-655 several times a day.  It was really annoying and one of the reasons I switched to a DIR-825 and interestingly enough, my connection would become stale every 57 minutes on the dot.  It was really weird, I would still be connected, I just couldn't connect to anything on the other side of the VPN.  Not sure if some settings my work uses don't play nice with dlink or what.  I had no issues prior to 1.21 though.

Anyway, I just switched to fios and use their router and get a stable connection all day.
