[pfSense Support] MAC based Access Control
How do I create a 'WAN' side firewall rule to allow a particular 'remote system based on its MAC address'
RE: [pfSense Support] how to prevent spams
Only authorized users are allowed thru SMTP AUTH method. But I guess one of the remote systems infected with virus should be spamming using the mail credentials configured by authenticated user. Since the spam generated is huge in numbers, how do I detect in pfsense firewall for such an abnormal traffic and block that particular remote IP in gateway level itself. Can I set a limit on WAN port on incoming traffic from a particular IP address ? Or can I set a rule in such a way that the remote IP will be automatically blocked, in case it exceeds the pre-defined threshold in wan firewall rule ? When I trace my Mail server logs, it looks like the remote IP is spoofed and a bogus address. So blocking that address may not be effective.

RE: [pfSense Support] vpn pass thru problem
I am using safenet softremote LT client software. My customer sent the security policy editor config file. So i just imported that in my safenet vpn client software and using. Hence i donot know what is the remote vpn server i am connecting to. My doubt is whether i need to explicitly configure anything in my pfsense firewall to allow the outgoing ipsec traffic?
