No internet when creating 1:1 NAT

[drwebster93]

I have two servers on my LAN that I need to map public IP addresses to.  So far, I have followed these steps:

1. Create a virtual IP for both addresses
2. Create a 1:1 NAT for each address
3. Create NAT rules for port forwarding

My issue is that the servers loose internet connectivity entirely every time I put the 1:1 NAT in place.  If I remove the 1:1 NAT, I regain internet connectivity instantly.  When I add it back, I loose it again.  Everything else on my LAN can still connect, it only affects the server whose IP is in the 1:1 NAT rule.  Any ideas as to what might be causing this?

I am using Comcast business class as my ISP, and I have the SMC gateway.  I have a block of 5 statics.  The setup works fine on the old Cisco router I am trying to replace with the new pfsense box.

Thanks!!!

Post screens of your NAT rules and WAN firewall rules.  Obscure any public IPs before you post.

You need to power cycle your cable modem after changing devices like that. Also make sure your Cisco router has that IP removed before you power cycle the modem.

Thanks guys!  I will try again later today and will be sure to reboot my modem this time.  If that doesn't do it, I will post the additional information requested.

Rebooting my Comcast modem solved the issue!  Thank you VERY much!  ;D
