Forwarding DNS queries in Chrome

Due to ultra strict corporate firewall, I've been utilizing a SOCKS5 proxy (ssh -D) to tunnel http content. Unfortunately, the DNS servers used by the organization block certain content using null routing, and the corporation goes in and adds in its own blacklist (which display the convenient "This content is restricted" message). Question -- how do I force chrome to forward DNS queries to the proxy as opposed to using the local DNS servers? I can access content that the corporation has on it's blacklist, but things that are null routed by whoever hosts the DNS servers for us (we don't host our own) are not accessible due to DNS queries not being passed through to the proxy. I know Firefox has some settings natively that allow for this functionality and was wondering, outside of extensions, if it's possible to force this behavior in chrome. Thanks.
 
Chrome uses getaddrinfo(). You're hosed unless you can use different DNS servers than the one the office provides (usually busticates everything in an environment that blocks everything)
 
uhhhh... yeah...
it's not your network, don't bypass their restrictions.
 
No help from me. Read the forum rules. If I were network admin there I'd completely null route you from everything on the internet.

I remain somewhat shocked that corporations take an "Allow everything, block specific" approach to internal networks and firewalls.

Anyway...sorry, OT for the thread, just mentioning it.

Q. How do I bypass/circumvent my school, work, or service provider's firewall/proxy/security?

You don't! Those types of devices are in place for a reason and if you choose to attempt to go around them you merely open yourself up to being expelled/fired.

Keep in mind that (a.) many people who frequent this forum are network administrators who's job it is to monitor and maintain the networks you guys use, and (b.) it opens the forum owners up to legal action should something illegal happen with help from this forum.

Should you have a truly legitimate reason for raw access to the web you must ask your network administrators for permission. Period.

Last guy I caught using a proxy to circumvent our web filter got his internet access removed completely. He was fired a couple of months later for looking at porn on his personal laptop.
 
My manager needed specific access to a resource that was null routed. I realized the DNS leak was the reason I was unable to access the specific resource he requested. As far as I can tell, whoever hosts the DNS server for the company automatically null routes certain resources, and whoever the liason is in the IT department (what would be the system administrator, of which we have no one in the building with that specific title) has to specifically request those resources to be routed properly Considering we don't really have an IT department to speak of (outside of the help desk, which is outsourced), I've been asked if I could access the resource since apparently it's kind of important to my manager for one particular reason or another. If I personally wanted to circumvent the network restrictions, I would just pop in my Ubuntu liveCD, ssh in with X11 forwarding and go to town, but that's not the point of this at all. I'm just trying to figure out if there is away around the DNS leak in chrome so that he can access whatever the hell was so important for him to gain access to instead of waiting for probably weeks before the request for access is even submitted, so the holier-than-thou follow the rules shit can really just go.
 
It's still bypassing company policies, manager or not.

If its so important go on it with your phone or at home.
