loadbalance with 2 or more links

loadbalance with 2 or more links

[pauloric]

Hi 

I have been working with iptables and now I'm  migrating to nftables ( BTW really nice job netfilter team 80)  ).

I have been using http://fatihusta.com/2015/03/07/network/linux-wan-load-balancing/  since nexthop is not working for a long time.

Studing nftables wiki I found 2 solutions:


a) nftbl   https://github.com/zevenet/nftlb

nftbl looks like very good, but very complex for a single load balance solution.

or

b) nftables + nat/loadbalance  https://wiki.nftables.org/wiki-nftables/index.php/Load_balancing

98% is ok using iptables-restore-translate as example.


As I've been using  iptables + mangle + iproute, what is easiest solution to use with 2 or more links ??  


Best regards

Both uses the same techniques, mainly for load balance services but
probably you could use it for uplinks load balancing as well if you
isolate the network interfaces to each router and put the load
balancer as the default GW in your LAN.

We've been using iproute for load balancing uplinks, but it shouldn't
be difficult to add it in nftlb as well.
