Zabbix not sending Community String

[wolfpack]

Hello,

I am trying to set up zabbix1.0 on Fedora3_x86 for monitoring network devices (in this case a Cisco PIX).
I can successfully do a snmpwalk from the zabbix server to the PIX firewall. However from tcpdump captures it looks like Zabbix is not sending the configured SNMP community string while polling. I have set the host exactly as per documentation ( SNMPv1 host, Community str etc). Any ideas ?

Thanks,
