I've setup a site to site OpenVPN connection between two locations (my home and business) successfully. I have a Asus RT-N16 at home acting as the OpenVPN Server and a ASUS WL-520gU at the business acting as a client.
The OpenVPN is working, however I'm getting the following error in my server logs:
RT-N16 daemon.err openvpn: ASUS_WL-520GU/xxx.xxx.xxx.xxx:yyyy write UDPv4 : No buffer space available (code=132)
When this happens the VPN is very slow.
I've added the following line to the Administration->Scripts->Init:
But it doesn't seem to help.
I have a USB HD attached to the RT-16N and believe I have swap setup correctly.

Any help is appreciated. Thanks
