True aggregating is difficult to achieve. I have one setup running that
uses 2 OpenVPN tunnels ending on different IPs of the same OpenVPN
server and link them together with 'eql' devices. This increases the
bandwidth inside the tunnels for different connections, but a single
connection still doesn't show a benefit.
Setting it up is quite a bit of hassle as you have to tell OpenVPN the
IPs of the other tunnel are just fine inside as well as the linux
network devices to accept 'martian' packages by setting the involved
devices rp_filter to 0 in /proc/sys/net/ipv4/conf/*/rp_filter.
The setup is non-trivial and you won't be rewarded with overwhelming
stability according to my experience.
