enough for a reasonable install, plus a few smallish programs

1st problem, I doubt any isp in rockingham support 56k connections. We
(Netway) have a POP down there and we find the lines to be crap at best,
many customers struggle to get 33600 most of the time.

Yes we do, basically we need to ensure the same IP is assigned to both
modems which they dial into, otherwise each modem would have a different
ip - which no doubt would caudse problems, We also need to set it up so
that the traffic is sent reasonably equally (ballanced) thru the 2 lines.
So in short, yes u need to have the isp do something _most_ of the time

yeh thats plenty i would think.

We have the same policy, should our server find you on twice, both
accounts get disconnected. I dont know our official price off hand (its
not something people ask for everyday) but i suspect paying for 2 accounts
would be reasonable (ie for netway coastlink, 2x$30/mnth, for iinet
2xwhatever they charge in rockingham)

> Does anyone have a good recommendation for an ISP in the Rockingham area. 
Netway Coastlink :) (sorry bit biased here) www.coastlink.com.au

As a side note, when you say telstra was quoting him $x for the isdn,
where was that isdn going to? not perth i hope!
Most providers in rockingham would happily have isdn customers, which
would definately be cheaper since telstra charge based on distance for the
isdn by cable.

Will be interested to see comments from other ispy people, not sure if we
have any iinet guys on the list, but we have networx and q-net at least
(do either of you have pops in rockingham/mandurah????)
