Hi,
I would really appreciate someone's help. I spent too much time and having no clue what's wrong..
I have a setup of simple lab in EVE-NG. I've added a static IP to Firepower6 FMC (version 7.2.0) and works normally. I've tried adding a static IP and over DHCP to Firepower6 FTD (version 6.2.0) and it also works ok. Ping from PC to FTD and FMC goes through. In expert mode both of the devices can ping each other, PC, Google DNS.. But I got stuck with adding the FTD to the FMC. Always after 2min 6sec I get and error saying "FTD-1: Registration timed out. Please check connectivity and registration id".
Connectivity is ok, key is def ok. I've also tried adding a static route to the br1 interface pointing to the FMC but without success.

I've also tried switching from QEMU Nic tpl(e1000) to e1000, vmxnet3 and few others but again without success. In some of them instead of br1 it's eth0 but still the same issue. What I'm doing wrong?
Solved! Go to Solution.

@Felixsson1 do you mean FTD version 6.2.0? You cannot manage FTD 6.2.0 with FMC version 7.2. FMC 6.6 is the last version that can manage FTD 6.2.X

When you do "ping system 192.168.100.100" from FTD what do you get?
Also try from expert mode as root user on FTD "telnet 192.168.100.100 8305".
If both of those work, from FMC as root user try "telnet 192.168.100.101 8305".
(The control channel between the two devices uses tcp/8305, initiated from either end for various purposes.)

Hi Marvin,
Thanks for the reply.
1.) Ping from FTD to 192.168.100.100 is ok.
2.) Telnet from FTD 192.168.100.100 8305 doesn't work. Says "connection refused".
3.) Telnet from FMC to FTD over TCP 8305 goes through.
EDIT:
On FTD:
admin@ftd-felix:~$ netstat -pan | grep 8305
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 192.168.100.101:8305 0.0.0.0:* LISTEN -
On FMC:
admin@fmc-felix:~$ netstat -pan | grep 8305
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

So it appears the sftunnel process on FMC is down or otherwise not listening on tcp/8305. You can try to restart just that process:
pmtool restartbyid sftunnel
...or restart the whole FMC to get it going again. If both those fail, then a TAC case is likely in order.

I've tried restarting the process but with no help. Also the same thing with restarting the FMC. TAC case is not an option, don't have a support with this one.
I've tried with 4 different FMC versions and I'm getting the same problem. I can accept it with one or two but on 4 different FMC images versions.. uhh
EDIT: I've found an issue. Sftunnel si running but the .conf file is corrupted.

Perhaps inquire in the EVE-NG forums. I've not had this problem on over 100 FMCs that I've worked with, both virtual and physical.
08-18-2023 05:31 PM
I'll do that. But what is more strange to me about the whole situation is that I've tried with at least 5-6 different versions of FMCs and I've also tried in GNS3 but without luck.

Hi Rob,
Thank you for the info, I wasn't aware of that. I have them both fully operational. Thanks!
