You could set it at the router level in sys-net using a mangle table. This is available for both iptables and nftables. I've done this with iptables in the past and I dont recall issues with conntrack and connected clients. ymmv iptables has tcp-MSS patch that allows you to hit this in FORWARD rules - dont know if similar is available for nftables. unman -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
