pve-firewall: best practice to minimize firewall overhead for glusterfs?

[swartz]

Scenario:
Two PVE servers have dual NICs each. One NIC (eth0) in each server is connected to the wider network.
Machines are also directly connected to each other (via eth1) ports for glusterfs replication.

Once enabled, pve-firewall filters all interfaces.
What is the best way to minimize iptables overhead since there is no need to filter traffic on the eth1 iface?

Is this as good as it gets?
IN ACCEPT -i eth3

Hi,
Yes this will work, but to be sure have a look on the iptables rules after changing.
Have in mind the first rule which match rules.
You can do this also on the gui.
this setting you must set on the node at the firewall tab.
