Здравствуйте. Помогите пробросить пор в PF. Стоит freebsd 7.2 настроен PF. Хочю пробросить порт на почтовый сервер который находится в сети за PF -ом.
Пробовал таким способом:
rdr on $ext_if proto tcp from any to $external_addr/32 port 25 -> 10.10.0.211 port 25
не получается, И таким способом:
nat on $ext_if proto tcp from any to $int_if port 25 -> 10.10.0.211 port 25 тоже не получается.Вот конфиг:
