I have a SBS 2011 and a RV042 router. I was going to try Forefront Online For Exchange 60 Day Trial to see how it cleaned up spam, virus etc. Well to accomplish this I have to configure the router to only accept email from Forefront's IP addresses about 13 ranges in all. Has anyone tried this and is it even possible with the RV042 router? Thanks!

RV042 supports 30 entries of port-range forwarding and 50 entries of access rules.

So would I make an access rule for every IP or IP range? So set up 13 access rules and port forward like normal? If I creat a rule does it then by default block everything else on that port? or does there have to be a "Deny" rule some how? Thanks for your help!

Yes, you would need to add 13 Deny rules followed by 13 Allow rules, one for each IP range.
Here is a related discussion thread.

Is this how you would do it? and if so how do you decide priority? Thanks for the help!

Priority = 1 has the highest priority.
You only need one Deny rule placed at the bottom of the table as the others are duplicates.
You should have a forwarding rule that forwards SMTP to an internal IP address. The allow rules should have Destination = the internal IP address.

Thank you Tekliu, I thought the Deny rule was duplicated but I misunderstood your earlier post saying I needed 13 Deny rules Ok I do have SMTP traffice forwarded to my 192.168.1.2 address so I cleaned up the table to this. Does this look correct? Also would you turn on packet logging ?

Gilbert, You can get rid of the #14 as it will be denied in the 2nd from last Deny WAN-Any-Any
