Thanks for the reply. I do not get any packets on the outgoing
interface (eth0) for the IPIP protocol. There is only 1 nic.
"tcpdump -i eth0 "ip proto \ip" => not results.
I ran the following commands.
ipvsadm -A -t VIP -p -s wlc
ipvasadm -a -t VIP -r RIP -i
ip a a VIP/32 dev eth0
Output of ipvsadm -L
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP VIP:0 wlc persistent 360
-> RIP:0 Tunnel 1 0 2
The server has a single NIC. IPtables allows for all outgoing and
forwarded connections.
