block_local_needed()

bool block_local_needed

(

const struct route_list *

rl

)

Get the decision whether to block traffic to local networks while the VPN is connected.

This definitely returns false when not redirecting the gateway or when the 'block-local' flag is not set. Also checks for other prerequisites to redirect local networks into the tunnel.

Parameters

rl	const pointer to the struct route_list to base the decision on.

Returns

boolean indicating whether local traffic should be blocked.
