Hello,
I am a Security Engineer and I am in charge of the upgrading of the Authentication Manager from version 8.1 SP1 patch 15 to version 8.3 patch 3. The upgrading is going to happen first in a clone machine of the original Authentication Manager in a isolated environment, therefore we changed the IP from eth0. The problem is the iptable erased completely, is this normal?, Is this an automatic procedure do it by the authentication manager? and how can I restore the iptable?. Thank you very much.
All network changes to an already set-up RSA Authentication Manager instance must be done using the Operations Console web page, administration, appliance network settings. If you initiated the IP address change on this page, iptables config is retained. If you did it via some other means such as Linux command line, that is not recommended nor supported.
If all iptables work was done correctly, then there would (or could) be a backup of the iptables generated by iptables-save
/etc/sysconfig/iptables.bak
