Ok, I have nftables.service active and stopping it I'm able to ping the host from the guest. So this was the problem. Thank you very much =) If I remember well, I configured nftables.conf using one of the Debian defaults. Since it's a topic I still have not find the time to study, I'm a little blind on what I can do to fix the configuration... /etc/nftables.conf:: #!/usr/sbin/nft -f flush ruleset table inet filter { chain input { type filter hook input priority 0; # accept any localhost traffic iif lo accept # accept traffic originated from us ct state established,related accept # activate the following line to accept common local services tcp dport { 22 } ct state new accept #tcp dport { 22, 80, 443 } ct state new accept # accept neighbour discovery otherwise IPv6 connectivity breaks. ip6 nexthdr icmpv6 icmpv6 type { nd-neighbor-solicit, nd-router-advert, nd-neighbor-advert } accept # count and drop any other traffic counter drop } } -- ~ Sandro ~
