webservice client - Is it OK to piggyback web services? -

i writing client-server application there little app on users' laptops in company.

they need read/write sql info (only little amount, query see lastly logged something).

i don't want expose internal sql server "any" host on internet, have http access (trusted) net web host. planning write web service on our internal iis server can consumed external web host. plan have sec web service on external host target clients.

essentially workflow be:

client queries external host via webservice -> external host queries internal web server via web service

is on complex, or accepted practice avoid opening http/s traffic on firewall host internal server?

while can work little bit of on complication. have 1 web service hosted , inquire network team help expose , secure external facing side of it.

for illustration server might have 2 network cards 1 internal , 1 external traffic. dns can route external address internal ip address. reason on complicating issue alter on web service require alter @ 2 places. have 2 points in chain can break. pattern implementing called facade , used abstract details away come think of more case of proxy design pattern.

another potential issue see type of service can exploited of more unsavory developers out there(hackers) harvest user names. mention nil how people authorize against service , description sounds open use. hunch have not provided plenty info around this.
