Én is erre gondolok, de nem jövök rá hogy hogyan lehet megcsinálni a megfelelő tűzfal és routeing szabályokat. Jelenleg ennyi a tűzfal:

config defaults
    option input 'ACCEPT'
    option output 'ACCEPT'
    option forward 'REJECT'
    option synflood_protect '1'
config zone
    option name 'lan'
    option input 'ACCEPT'
    option output 'ACCEPT'
    option forward 'ACCEPT'
    list network 'lan'
config zone
    option name 'wan'
    option input 'REJECT'
    option output 'ACCEPT'
    option forward 'REJECT'
    option masq '1'
    option mtu_fix '1'
    list network 'wan'
    list network 'wg0'

    option name 'Allow-Ping'
    option src 'wan'
    option proto 'icmp'
    option icmp_type 'echo-request'
    option family 'ipv4'
    option target 'ACCEPT'

    list icmp_type 'destination-unreachable'
    list icmp_type 'packet-too-big'
    list icmp_type 'time-exceeded'
    list icmp_type 'bad-header'
    list icmp_type 'unknown-header-type'
    list icmp_type 'router-solicitation'

    list icmp_type 'router-advertisement'
    list icmp_type 'neighbour-advertisement'
    option limit '1000/sec'
    option family 'ipv6'
    option target 'ACCEPT'
config rule
    option name 'Allow-ICMPv6-Forward'
    option src 'wan'
    option dest '*'
    option proto 'icmp'
    list icmp_type 'echo-request'
    list icmp_type 'echo-reply'
    list icmp_type 'destination-unreachable'
    list icmp_type 'packet-too-big'
    list icmp_type 'time-exceeded'
    list icmp_type 'bad-header'
    list icmp_type 'unknown-header-type'
    option limit '1000/sec'
    option family 'ipv6'

    option src 'wan'
    option dest 'lan'
    option proto 'esp'
    option target 'ACCEPT'

    option name 'Allow-ISAKMP'
    option src 'wan'
    option dest 'lan'
    option dest_port '500'
    option proto 'udp'
    option target 'ACCEPT'
config redirect
    option dest 'lan'
    option target 'DNAT'
    option name 'SSH'
    list proto 'tcp'
    option src 'wan'
    option dest_ip '10.13.6.1'
    option src_dport '4173'
    option dest_port '4173'
config redirect
    option dest 'lan'
    option target 'DNAT'
    option name 'luci'
    list proto 'tcp'
    option src 'wan'
    option src_dport '80'
    option dest_port '80'
    option dest_ip '10.13.6.1'

Semmi extra, egy luci és egy ssh van nyitva. Ezeket Én vettem fel.
