Subject Re: SSVM cant route to MS, Iptables keep self-updating
Date Tue, 05 Apr 2016 12:36:51 GMT
I've checked the host iptables just now...there were rules accomodating the
SSVM and CPVM.
But I've made the mistake of flushing the iptables rules without any backup.
 Now Iptables -P, -L has:

-P INPUT ACCEPT
-P FORWARD ACCEPT
-P OUTPUT ACCEPT
-A INPUT -j ACCEPT
-A INPUT -j ACCEPT
-A FORWARD -j ACCEPT
-A OUTPUT -j ACCEPT
Chain INPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere
ACCEPT     all  --  anywhere             anywhere

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
ACCEPT     all  --  anywhere             anywhere

One more thing, this setup is self-hosted.The MS and host are on the same
machine.
