Мусора, конечно, там много, но он скорее не критичен и связан с выбранной политикой "разрешено всё, что не запрещено" ИМХО, не лучший вариант для шлюза между локалкой и интернетом, но это не мне решать.
С учётом того, что применена прозрачная маршрутизация непонятно назначение правил
-A POSTROUTING -o eth2 -j MASQUERADE
-A POSTROUTING -d 192.168.54.6/32 -p tcp -m tcp --dport 80 -j SNAT --to-source 192.168.54.254
Предлагаю убрать ,как минимум первый
sudo iptables -t nat -D POSTROUTING -o eth2 -j MASQUERADE
а если неизвестно назначение, то и второй
sudo iptables -t nat -D POSTROUTING -d 192.168.54.6/32 -p tcp -m tcp --dport 80 -j SNAT --to-source 192.168.54.254
