#871 new Bug / Defect
DHCP gateway stripping does not remove DHCP option 121 0.0.0.0 routes

Description
DHCP allows defining classless static routes using option 121. However, according to [RFC 3442](https://tools.ietf.org/html/rfc3442), if a route is defined using this option, option 3 (default gateway) must be ignored. Instead, the default gateway must be defined as the route for 0.0.0.0/0, using the same 121 option.
OpenVPN doesn't seem to strip this route from option 121 when server-bridge with dhcp gateway stripping is enabled.

Sorry to bump this, but I'd be happy to contribute with a patch if you point me in the right direction (like where can the latest source be downloaded, and how to send the patch itself (pull request, email address, etc).
