Description |
This article describes the behavior of debug flow when the destination address is created as IP pool on FortiGate. |
Scope |
This applies to the following scenario where the destination IP is the same as the IP pool on FortiGate.
The following is the scenario:
Client (10.4.25.192) -> FortiGate (IP pool - 10.4.1.30) -> Port2 Destination (10.4.1.30) |
Solution |
The following is the static route for the destination 10.4.1.30 via Port2:
FGVM (VDOM_TEST) # get router info routing-table database | grep 10.4.1.30
The following is the output when the debug flow is executed for the traffic:
FGVM (VDOM_TEST) # id=20085 trace_id=147 func=print_pkt_detail line=5665 msg="vd-VDOM_TEST:0 received a packet(proto=1, 10.4.25.192:1->10.4.1.30:2048) from ssl.VDOM_TEST. type=8, code=0, id=1, seq=217." id=20085 trace_id=147 func=fw_local_in_handler line=431 msg="iprope_in_check() check failed on policy 0, drop"
There are 2 important information on the debug output shown above:
1) The traffic is stopping at the 'VDOM_TEST' instead of Port2 as configured on the static route. This can be seen from the output 'find a route: flag=80000000 gw-10.4.1.30 via VDOM_TEST'.
2) There is no matching Policy created for the destination traffic which explains the output message 'iprope_in_check() check failed on policy 0, drop'.
Solution:
Remove the IP pool or change to another IP pool for SNAT communication. |
