MikroTik

Hi there.
Apologies, I am a video editor, not a network guru, so please bear with me!

I work for a very large corporation and use various laptops and PCs for editing and media design work. I also look after a large number (Currently over 100) iPads that belong to a client. All these resources need to connect to the internet for program updates. Our corporate network accesses the internet via a proxy and therefore I need to enter the proxy details and my username and password into every device to get it to connect. This is a pain, particularly on the iPads, as this info has to be deleted before I can send them out each time.

Would it therefore be possible to set the RB751u that I currently use to provide wireless access for the iPads into our network to hold the proxy details and forward all internet requests to the proxy server?

IE:
iPad ------> Wireless Router [Router supplies Proxy divert]---> Corporate proxy---> Internet


The proxy settings on the PC are as follows: globalproxy.XXX.com Username [domain/USERNAME] Password.
My thought was if a script or something ran and this directed all traffic to the authorised proxy. I would therefore just need to conect to the wireless network to update the devices and not need to enter usernames and passwords each time.

Thanks for all your help in advance!

You could masquerade out on the LAN connection, and share the wireless.
You can then use dst-nat to catch all dst port 80, and forward to the mikrotiks own web proxy.
You can then setup the mikrotiks web proxy to use a parent proxy, and put the authentication details in there.

I would first test that the authentication works, so set your PC to use the mikrotik web proxy, and it to use your corporate proxy.
