Hi John, LVS can use iptables but doesn't always...
Basically firewall mark configurations are marked in iptables so will show in the iptables-save output. LVS will also use conntrack from iptables if available for NAT mode. However, for a simple single port virtual service you wouldn't see anything in iptables-save at all.
