I have policy routing set up which works great for outgoing connections.
#NETMAP ENABLE ZERO COPY WITH HOST STACK DRIVERS#
Of course if you want the netmap-enabled drivers statically built in the kernel image you need to compile a custom kernel. Hostname1/IP address, Hostname2/IP address, Hostname3/IP address Host name Host name associated with the IP address. Consider that the point of this AUR package is to spare the user the compilation of a custom kernel, while still benefiting from the netmap-enabled drivers - e.g. Doing so lets netmap checking succeed when the remote node connects to the local node using any of the possible outgoing IP addresses. This causes all incoming connections to fail over WANs 2 + 3. The outgoing IP addresses are then contained in the local node netmap entry for that remote node. Incoming connections to a ULA IP over WAN2 (translated) should then go back out WAN2, but instead they go out WAN1 (the default gw). Outgoing connections work fine and I can policy-route through the different ISPs. For example, I can ping the translated IP for WAN1, but the translated IPs for WANs 2 and 3 time out unless I change the default route to go out WAN 2 or 3. In this paper, we will only consider zero-copy mode as it has the best performance. AF XDP is the mechanism for which XDP can di-rectly redirect packets up to an application in user-space with zero-copy semantics. For some reason incoming connections only work for the default route, not ISPs #2 and #3. Stack Network card Figure 1: XDP can process special user space applications in the kernel driver. I have an ip6tables router with 3 WANs, each supporting IPv6.
