Difference in IPv4 v.s. IPv6?

Hi, System is a Fedora 33 VM running firewalld-0.8.4-1. I have: [root@f33k ~]# firewall-cmd --get-active-zones drop   interfaces: enp1s0 enp1s0 has addresses 192.168.122.26 and 2001:b030:112f:2::53. If I try to ssh to it from another system I get.... [egreshko@meimei ~]$ ssh 192.168.122.26 ^C Meaning it "hangs" until I ctrl-C it or it will timeout at some point if left alone. But I get this using the IPv6 address [egreshko@meimei ~]$ ssh 2001:b030:112f:2::53 ssh: connect to host 2001:b030:112f:2::53 port 22: No route to host So, is this a difference in how the FW handles IPv6 or due to how IPv6 works on the source side? Thanks, Ed
