[strongSwan-dev] [PATCH] dhcp: Allow binding of socket to particular interface

[Thomas Egerer]

In certain situations it is desirable to bind the send/receive sockets
for the DHCP address allocation to a particular interface. With this
patch the strongswan.conf option charon.plugins.dhcp.interface can be
used to restrict the DHCP communication to a configurable interface.

Hello *,

I found that the dhcp plugin tries to allocate an IP-address on the
wrong interface and since I cannot modify the routing rules of the
system strongswan is running on, the only sensible solution to
solve this problem is binding send/receive socket to a particular
interface.

Cheers,

Thomas
