Looks like firmware 3.3.2 breaks access to open ports using the external address from inside the firewall (I'm only using WAN2). It just seems to sit there for 30 seconds or so and then returns nothing:

Tried:
http://www.draytek.co.uk/support/download/v2820_3321_232201_A.zip
which i assume is the same as:
ftp://ftp.draytek.com/Vigor2820/Firmware/V3.3.2.1/Vigor2820%20V3.3.2.1%20AnnexA%20232201.zip

And:
ftp://ftp.draytek.com/Vigor2820/Firmware/V3.3.2/Vigor2820%20V3.3.2%20AnnexA%20232201.zip

But this firmware got back the funtionallity:

ftp://ftp.draytek.com/Vigor2820/Firmware/V3.3.1.2/Vigor2820%20V3.3.1.2%20AnnexA%20232201.zip

Hope its the right one (i.e. the 3.3.1.2 version I used to have).

[Edit]
Above is a little confusing here's a fuller explanation:
www. points to my router's WAN2 address and port 80 is forwarded to a web server on my network. With the older firmware I can browse www. from inside my network (as well as using it's real IP address), whereas with the later firmware it stalls after 30 seconds with the external name/address.

i think i've got the same problem. I run a webserver, and it can no longer be accessed within the network after upgrading to 3.3.2.1

however it looks like it can still externally.


EDIT: Ive just downgraded to the 3.3.1.2_232201 and its now working fine again.

All working fine for me. Have a web server and email server that are using open ports and both are accessible from inside the network as well as outside. Using version 3.3.2.1_232201.

I too a having a problem with an internal server that cannot be access within the network and now the new firmware has slowed the draytek unit down.
I am trying to flash back the 3.3.1.2 but takes forever to access the web front end of the router look like draytek have stuffed up again.

just tested and the router slows down when a program like outlook tries accessing the exchange server. Outlook is configured to access the server via the web but is sitting local to the network and was fine on 3.3.1.2 but no good on 3.3.2.1 anyone got any ideas?

ok so more testing shows changing the management port to 8080 keeps the router working fast but port 443 cannot be fowarded to my server why??? Must be a port issue.
