unable to access FP MC via Web GUI

[AdamBudzinski]

I have configured the CISCO FP MC VMware Virtual Appliance with the initial IP management address settings and I'm unable to access the Web GUI. I can ping the IP (I can see packets arriving on the FP MC via tcpdump) and when trying to access via https://x.x.x.x I can see that SYN packet arriving from my laptop to the FP but no SYN/ACK being send from the FP MC towards my laptop. Any ideas on how to troubleshoot this further ?

Ok, I've reseted iptable rules and it worked.

How could I disable iptables ?

iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
iptables -t nat -F
iptables -t mangle -F
iptables -F
iptables -X
