Intranet on BT 2Mb ASDL line slow from other BT BB sites

Now that the pain of BT's total upgrade cock-up is fading, we are left
with only one issue: speed (!)

Head Office is hosting a Linux server running eGroupware for our
Intranet services. Ever since the upgrade to a 2Mbit service, some of
our other sites have noticed that their access to the Intranet has
slowed dramatically, but not to other general Web sites - these sites
don't use us as an Internet gateway or for DNS services and the like.
The sites having the problem are also with BT business broadband, but
accessing the site from a couple of Zen-hosted accounts seems OK.

The only major change at HO was reconfiguring the (Draytek 2600+) router
for the 5 direct IP addresses - one of which is forwarded to an SQL
server and another to the Intranet server. I have checked the router's
setup several times to make sure there's no quirks or issues and I'll be
able to try another router in about a week's time.

Has anybody else encountered such a problem (slow BT-to-BT surfing) -
I'll ask BT in due course but I thought I'd try this more knowledgeable
channel first!

TIA

What version of firmware are you running on the Draytek?

Not on BT but another scenario. An upgrade to the Draytek firmware
solved it.

Firmware is 2.5.4UK

Seems DNS-ish to me - I'm actually going to try bypassing the Draytek as
a DNS proxy as I've heard some negative things about Draytek's DNS
implementation.

Yep,

This seems to have fixed it.

I have removed the Draytek as the DNS forwarder address from the local
DNS server and pointed the DNS server directly to BT's bank of DNS
servers instead and things are much faster.

Hiram,

Contrary to other postings in the thread I don't seem to have this fixed
- any ideas?

The draytek has the second subnet option - have you configured that?
I seem to recall we did have trouble where the second subnet was used
in some way.

The firmware level you posted before seemed up to date enough.

2nd subnet is set to the IP address and subnet given to us by BT:
81.x.x.x and 255.255.255.248. 'For IP routing usage' is turned off on
the advice of Draytek.
