The WAN port of my VPN server is connected to a router/firewal and thus to ASDL line. For some reason the router/firewall doesn´t let me add multiple VPN to the same machine. I replace the ADSL line with a PPP interface and now it’s working, however i still have to figure out whats wrong with the router.
Out of context: In my configuration (2 PPP links on one side and 1 PPP on other side) i get lots of out-of-order packets, leading to a very small BW increase. Any thoughts? I have read about changing the tcp reordering parameter in the bonding driver, does it worth it?
