    Hi, and welcome to the forums!
    policyid=0
    This is the implicit deny policy at the end of the policy table. If traffic does not match any policy then this policy will deny it finally. You can suppress logging implicit policy traffic. The option depends on the version of FortiOS used.

    Oh, but why are policy 0 deny ? What could cause this log generated? Addition to deny log I have seen allow log.↓ and what is mean " transip=noop" date=2014-09-22 time=09:04:24 logid=0000000013 type=traffic subtype=forward level=notice vd=VDOM-1 srcip=XXXX srcport=27431 srcintf=" Vlan-1169" dstip=XXXX dstport=2195 dstintf=" Vlan-3501" sessionid=2690748667 status=close policyid=100040 dstcountry=" United States" srccountry=" Reserved" trandisp=snat transip=XXXX transport=27431 service=TCP_1024_65535 proto=6 duration=35 sentbyte=183 rcvdbyte=128 sentpkt=4 rcvdpkt=3 date=2014-09-22 time=09:04:21 logid=0000000013 type=traffic subtype=forward level=notice vd=VDOM-1 srcip=XXXX srcport=28849 srcintf=" Vlan-1169" dstip=XXXX dstport=2195 dstintf=" Vlan-3501" sessionid=2690762802 status=deny policyid=0 dstcountry=" United States" srccountry=" Reserved" trandisp=noop service=TCP_1024_65535 proto=6 duration=0 sentbyte=0 rcvdbyte=0

    As I said traffic that is not matched by any policy is implicitly matched by policy 0 and discarded. " transip=noop" refers to NAT in NAT/routing mode. In this case, there is no NAT rule. Value can be " snat, dnat, noop" . Maybe it would be a good idea if you got the " Log Message Reference" for FortiOS v5, available on http://docs.fortinet.com . All field names are documented, for the traffic log and all other log sources. (From that, I deducted that your FGT is running FOS v5 - " subtype=forward" is only introduced in v5).
