Firewall and IDS/IPS Evasion - Medium Lab

I’m currently stuck on the “Firewall and IDS/IPS Evasion” Medium Lab. I’m having trouble finding the solution and would appreciate some assistance.

Could you please provide me with any hints, tips, or solution approaches for this step? I’ve tried using the relevant tools, but I haven’t been able to achieve the expected result. What commands should I try or what approach should I take?

Any help would be greatly appreciated. If you need any further details, please don’t hesitate to ask.

Thank you in advance!

not sure if you’re still stuck on this. this one drove me insane too. easy way is to just connect to the port with a simple tool and it will display a banner.
