ufw - доступ к локалхосту по порту 80

[The Green Side]

Добрый вечер!

Есть сервис, работающий в контейнере по адресу 10.81.65.206, порты 80 и 53
Открыл к нему доступ из локальной сети 192.168.1.0/24 по этому мануалу

Правила, которые я добавил в /etc/ufw/before.rules

Код: [Выделить]

# NAT table rules
*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]

# Port Forwardings
-A PREROUTING -i wlp1s0 -p tcp --dport 80 -j DNAT --to-destination 10.81.65.206
-A PREROUTING -i wlp1s0 -p tcp --dport 53 -j DNAT --to-destination 10.81.65.206

# Forward traffic through eth0 - Change to match you out-interface
-A POSTROUTING -s 192.168.1.0/24 -o wlp1s0 -j MASQUERADE

# don't delete the 'COMMIT' line or these nat table rules won't
# be processed
COMMIT

В принципе мне этого достаточно, всё работает.
Но было бы удобно ещё открыть доступ с самого девайса по его локальному IP, например 192.168.1.45
Тогда девайс будет доступен с одинаковым IP и в браузере на нём самом, и в браузерах на всех других девайсах.
Попробовал изменить правила таким образом (ниже), но это не работает.
Как надо?

# don't delete the 'COMMIT' line or these nat table rules won't

P.S. Использую ufw, потому что
1) мне так удобнее
2) это разработка инженеров из Canonical, и именно Ubuntu я использую для своих серверов и контейнеров, хочу оценить преимущества этого инструмента в его родной среде

bezbo, не помогло. ufw перезапускал.

И ещё один момент упустил, маскарадинг для постоянного IP не нужен и даже можно сказать немного вреден.
