Must Start Now, Fix PfSense firewall and configure cpanel correctly on dedicated server

PFsense was installed on server to prevent attacks that been happening to server about 3-5 months ago, it crashed now and no one can enter the [login to view URL] server was virtualized , one for wordpress and another vps for chatserver to reduce attacks i think , whoever was working on it did not configure cpanel,so cpanel need to be configures on server as [login to view URL] in mind its a chatting site and it gets attacked daily so Pfsense configuration correctly and security is VERY IMPORTANT. Also the security certificate i think is installed but it isnt functioning correctly that need fixed too. Also need to check why emails from My domain is going straight to junk mail, i have a customised registration that require email verification sent by wordpress and it goes to junk mail , as well as a mailing list for registetered members that also go to junk mail when i email my members eventhough we never ever send junk emails. so the job is 1-fix pfSense firewall and make sure its 100% secured to handle my traffic keeping in mind site gets attacked always. 2-configure Cpanel correctly on server and security certificate 3- fix e-mail going to junk mail issue. 4- 30 days support and be available anytime site goes down cause of firewall or attacks till its configured correctly. 5- wanna do this while keeping current server architecture , so ust need to fix and reconfigure things to work correctly. 6- must start now and bring site online then start working as site been off line due to firewall PfSense issues for 2 hours. i am not sure entirely of how server is set up but i dont plan on changing it, i know it has vmware vmsphere nginx cpanel
