Cisco PIX 501 - Enabling SNMP Monitoring from outside (internet)

Posted on 2007-07-26
Last Modified: 2013-11-16
So, we have a Cisco PIX 501 that we have taken over monitoring.  However, we are trying to add SNMP monitoring via the outside interface in.  The current config I have on the PIX is included below with some omissions.  

What would be the proper config to add snmp polling from a specific ip, or subnet?  Say I want to be able to snmp query the PIX via it's outside IP (WAN Interface).  How would I accomplish this?  Also, how would I add in the config that all traps generated are sent to via the outside interface (Internet/WAN Facing Interface)

    We are still not able to do snmp queries against the outside interface after adding these changes into the configuration. Any other suggestions? Thanks for your help.
