Thanks a lot Jiggimi for your information. The main barrier that stop me from upgrading the firewall is the IPSEC VPN connection between my office and the remote office.
I came to know that the two locations should have the same firewall to keep the IPSEC VPN tunnel to function properly. I have the following questions to verify if I reinstall my firewall with the OpenBSD latest version :
1) Will the re-installation stops my IPSEC VPN connection since the remote office OpenBSD firewall has a different OS version (Beyond my control)?
2) What are the files that I should copy from my old firewall to the new firewall? ( pf.conf, sysctl.conf the entire ISAKMPD folder etc. )
3) Do I have to run any commands to activate the IPSEC VPN in the new firewall after I copy the content from the current live Firewall?
Thanks
