pfSense

I need to create internal port forwarding for SMTP with some exclutiosn, all SMTP goes to 192.168.0.15 except some IP address/alias (213.xx.xx.xx)

Firewall: NAT: Port Forward rule
LAN2 TCP 192.167.0.0/16 * ! 213.xx.xx.xx 25 (SMTP) 192.168.0.15 25 (SMTP) SMTP transparent2

So, if in rule exist !(not) - Firewall filter shows an error:
php: : There were error(s) loading the rules: /tmp/rules.debug:415: syntax error pfctl: Syntax error in config file: pf rules not loaded - The line in question reads [415]: rdr on { em1 pptp } proto tcp from 192.167.0.0/16 to ! port 25 tag PFREFLECT -> 127.0.0.1 port 19095
