| Summary | 0001708: Verify behavior if ICMP forwarding when single port is forwarded |
| Description | ICMP should be forwarded to the target system when a 1-to-1 NAT rule is created. These rules are created by the firewall, but there might be a missing PREROUTING rule, e.g.:
iptables -t nat -I PREROUTING -p icmp -d 1.2.3.4 -j DNAT --to 192.168.1.100 |
