Yes, sort of. I setup a NAT rule and a firewall rule. Maybe not both
necessary, but it works :->.
1) Go to Firewall->NAT then on the Inbound tab, click '+' to add a new rule,
then enter it as:
ext port range 161
NAT IP (ext IP): 10.0.0.1
Int port range: 161

2) I can't remember if (1) created a rule which I modified, or I created the
rule myself. But it is as follows: Firewall->Rules. Under WAN interface add
a rule that is:
source: IP of computer polling yours (assuming an external computer!)
Description: NAT snmp mrtg
Hope this helps!
