Advice on WAN lines

[manbo]

Hello all,

I hope this question is convenient for this group. My network is
expanding and more users and offices need to connect into my main site.
I was considering adding more DSL lines and leased lines to give the
best mix of quality, redundance, bandwidth and cost. I have, however,
been presented with leased line pricing that is very competitive
compared to DSL circuits and am wondering which of the following
scenarios will give me what I want:

1 x 4Mb/s leased line
or 1 x 2Mb/s leased line + 2 x 1Mb/s DSL circuits
or 1 x 2Mb/s leased line + 1 x 2Mb/s DSL circuits

What I am after doing is providing connectivity for:
..incoming/outgoing mail from main site
..remote user vpn connections into main site
..site-to-site vpn connections to main site

Can anyone tell me, from experience or knowledge, whether I am correct
in thinking that utilising a separate DSL circuit for each site-to-site
VPN, another for my remote user VPNs and a leased line for my main site
internet traffic and incoming / outgoing mail will provide a better
service to the remote sites and remote users than a single 4Mb/s leased
line?

Please point me in the direction of another forum or group to post this
to if I am in the wrong place.

Thanks.

From a performance point of view separate lines for each type of connection
will be the best, but this will add complexity to your environment as well
as higher prices.

Andrei,

Thank you very much for your reply. I was looking forward to some
response but this post does not seem to have attracted any attention.

Separate lines was my preferred solution, but I was looking for other
opinions, especially if someone had experienced this. It may be
slightly more complicated, but with under 5 lines I imagine it can be
managed fairly well.

Thanks again.
