I am new to
After having configured a virtual network (new interface
virbr0) with 2 VMs that should be able to communicate, I discovered that most ports are filtered.
For example, the two nodes are mutually reachable via port 22, but for other ports, for example higher than 9000, I get a
no route to host.
trying to connect to the port 80, that is open on host 192.168.122.125, this is what I get with tcpdump:
07:50:55.363767 IP 192.168.122.14.54483 > 192.168.122.125.80: Flags [S], seq 21091821, win 14600, options [mss 1460,sackOK,TS val 313139 ecr 0,nop,wscale 7], length 0 07:50:55.364204 IP 192.168.122.125 > 192.168.122.14: ICMP host 192.168.122.125 unreachable - admin prohibited, length 68
Why is this? Is it possible to remove some filters, to allow at least the nodes to be able to communicate on various ports?
