Firewall is down but all incoming connections are being blocked

Hi guys, I can't access to any port of my Mac from the LAN. Then LAN is working fine because I can access other services (printer, services under windows).

My macOS version: Mojave 10.14.6 (18G8022)

I started a tomcat process on port 8080 and I can access from the same computer (192.168.1.101):

nrossi@tmp$ curl -I http://192.168.1.101:8080

HTTP/1.1 200 

Content-Type: text/html;charset=UTF-8

Transfer-Encoding: chunked

Date: Wed, 17 Mar 2021 19:27:30 GMT

root@log$ sudo /usr/libexec/ApplicationFirewall/socketfilterfw --getglobalstate

Firewall is disabled. (State = 0)

root@log$ netstat -an | grep 8080

tcp46   0   0 *.8080         *.*          LISTEN  

Then I run the same curl command from other mac (192.168.1.106) and monitor tcp connections:

root@log$ sudo tcpdump -l -n -i en0 dst port 8080

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

listening on en0, link-type EN10MB (Ethernet), capture size 262144 bytes

From my other mac:

nrossi@~$ curl -I http://192.168.1.101:8080

curl: (7) Failed to connect to 192.168.1.101 port 8080: Operation timed out

Any help ?
