Re: UDP 3343 not allowed across interfaces on ASA

Jesserony · ‎12-12-2022

Hello Everyone,

We are trying to get a SQL cluster node to communicate on UDP 3343 from a host attached to our "DMZ" interface, to a host on our Inside interface. Packet tracer is saying the packet is dropped due to an ACL, but ive cleaned up our ACLs to allow IP any any. Could someone take a look? PT results and ASA config below.

Thanks,

Jesse

@Jesserony the network 172.30.43.x is your DMZ network, but your packet-tracer input interface you defined as "inside" - re-run packet-tracer with the correct input interface and paste the full output.

Jesserony · ‎12-12-2022

My mistake, thank you - this brings me back to the original question i had.

Look at the two packet traces below - one going from UDP 3343 to 3343. The PT output says its allowed, but doesnt show what the output interface will be. Now if i do 3343 to 3344, it does show the output interface.. Is that meaningful to you Rob?

@Jesserony this is probably a clue.

Do you have an existing connection?

Is real traffic working or not?

Jesserony · ‎12-12-2022

Yes, the connection works, ping and SMB are currently working between those subnets, it just doesnt seem to be liking UDP 3343 for some reason.

Rob Ingram · ‎12-12-2022

@Jesserony check local firewall on the server itself to ensure that port is allowed from the source.

Take a packet capture

Jesserony · ‎12-12-2022

Ok ill give that a try. Related question: When i run a packet trace does it somehow know there is an issue somewhere outside of the ASA? I was under the impression packet trace was completely simulated.

MHM Cisco World · ‎12-12-2022

DMZ and Inside same security level so you need below command
same-secuirty-traffic permit inter-interface

looks like it's already configured

MHM Cisco World · ‎12-12-2022

show arp in FW do you see the MAC address of next-hop 192.168.254.57

Jesserony · ‎12-12-2022

Yup, i can see 192.168.254.57 in arp.

MHM Cisco World · ‎12-12-2022

the server is in DMZ and it use 3343 ? or server in IN and use 3343 ?

MHM Cisco World · ‎12-13-2022

in this case there is many point the packet can drop on it,
but we want to mini our search,
you can use capture in ASA to find if the packet is receive and send to server through ASA FW.

I run lab show you how you can use capture in ASA FW
I have two interface IN and DMZ.

please note that you must use NO capture ......... after finish because this capture take large CPU/memory resource.

Jesserony · ‎12-13-2022

Thank you so much for the help! I will give it a try.
