Are you as fed up with my 2Mb upgrade as me yet...?

Seems to be working now, apart from email (can take up to 24hr for BT
cockups..er..changes..to propagate through their systems), but one thing
I have noticed is that ssh sessions timeout if they're left idle for too
long and also remote VNC connections sometimes do the same. Didn;t get
this on 512K.

We had 80%+ packet loss on Monday morning which might have explained it,
but things are rock(ish) solid now - anyone else seen this.

I can't think of anything tweakable that may affect this (MTU different
for 2MB??) but any feedback or comments would be welcome.

Interesting to watch someone having this done, but myself and some of my
business clients have ADSL from more than one ISP, so a bit of downtime
with one (or no service at all) doesn't lead to massive problems :-)

Having everything depend on one seems a bit too risky (I would still have
Highway as backup if BT had not required everyone move to BT Together a
few months back, as that was independent of ADSL kit in my local exchange
but I'd get a 56k modem into use if it all fell apart tomorrow :-) Peter

I agree - we're likely to move some auxillary sites to Zen and also
re-jig an existing ISDN link at HQ for this reason.

I am just sorting out what I inherited at HQ and now that certain
services (Intranet, remote backup and hosting our own mail server) will
be come more critical, I will be making sure that WE are able to cope!

We're only piloting the Intranet site at the moment and I'd already
ordered the 'redundant', off-site servers, but due to a delivery cock up
they arrived one week later than planned and so I could only get the
secondary Intranet server running 2 days into the outage.

In all events this was not a serious business outage but just a pain in
the ass that had me wasting time chasing BT to confirm that SOMEONE was
sorting it - shame you can't make one phone call and just know that
someone will call back (as promised!) when things are put right.

The 2Mb upgrade was part of our 'planning for the future' but thankfully
the project plan ensured that we'd not gone 'live' with anything major
at this time.

Looks like Draytek haven't got their multi-NAT/Multi-IP handling quite
rock solid - there's a thread about this specific problem on the UK
Draytek support forums. I'mm downgrade my opinion of Draytek kit from
10/10 to 9.5/10!

Can anyone tell me of their multi-NAT/Multi IP experiences with other kit?

TIA

Seems fine with ZyXEL kit - in my case a no-NAT Prestige 650H-E1 with
its firewall off on the WAN 1 port of a ZyXEL ZyWALL 35. The only thing
that doesn't work properly is multicast, which I would have liked to try
with the BBC Multicast trials that Zen peer with. That said, the release
notes of the P650H-E1 say that IGMP doesn't work - so that's probably
the reason.

ZyXEL's multi-NAT implementation seems to be well rated on all their
multi-NAT capable kit.

The ZyWALL 35 should get 3.63 firmware in the next few weeks, making it
a proper load balancing dual WAN router and adding certainly other
'missing' functionality, such as WPA if you have a wireless card
inserted, also DNS server capabilities.
