It sounds as though you have done all the right things - why don't you try replacing the "forwarding IP" virtual with a Standard network virtual (to enable easier troubleshooting - you can replace with a forwarding/fastl4 later).

 

Execute tcpdump -i0.0:nnn -s0 -XXX host a.a.a.a while you run telnet a.a.a.a 25 on one of your internal servers - what do you see?

 

What is a.a.a.a - is it in 192.168.227.0/24? What is output of tmsh /net show arp for IP a.a.a.a?
