I have try is and it works only in one direction (srv-a -> srv-b).
When I try to transfer files from b to a only some bytes are transmited
(seen in tcpdump). ssh from b to a is working.
the config looks like:
A:
auto ens2f0
iface ens2f0 inet manual
auto ens2f1
iface ens2f1 inet manual
auto bond0
iface bond0 inet static
address 10.0.1.11
netmask 255.255.255.0
network 10.0.1.0
slaves ens2f0 ens2f1
bond-mode 0
bond-miimon 100
bond-downdelay 200
bond-updelay 200
B:
auto ens2f0
iface ens2f0 inet manual
auto ens2f1
iface ens2f1 inet manual
auto bond0
iface bond0 inet static
address 10.0.1.12
netmask 255.255.255.0
network 10.0.1.0
slaves ens2f0 ens2f1
bond-mode 0
bond-miimon 100
bond-downdelay 200
bond-updelay 200
