Thank you for your response.
I did in fact consider a dedicated solution but having recently purchased
the server hardware and entered a 2y-long contract with the ISP, I really
don't think that would be an economically viable solution (not to mention
all the migration work). I previously looked into housing my servers
somewhere but there are no datacenters that offer such service in my area
and it would be a hassle having to go there everytime I need to scale the
HW configuration (and that happened a lot lately).
At this right moment, I have 43 open and 11 half-open connections for SMTP
on the mailserver and 30 open connections on port 80 for the webserver.
Unfortunaly the numbers vary much, especially between 5-10pm.
I know this might not sound very specific, but when I was connecting via
the cable the modem was basically acting as a bridge to the servers and I
never had any stability problems whatsoever. I would like to be able to
obtain the same results with my DSL line too.
BTW, I google'd for DM111PB but it only showed up Netgear products - are
you sure linksys makes one with the same name?
