Co prawda godzina późna ale udało mi się wykombinować: iptables -t nat -A POSTROUTING -j SNAT -p tcp --to-source 10.7.0.1 iptables -t nat -A PREROUTING -p tcp --dport 2222 -j DNAT --to- destination 10.7.0.2:22 efekt zamierzony został uzyskany, pytanie tylko na ile to bezpieczne? Muszę sobie jeszcze poradzić z polityka FORWARDU na DROP, bo testowałem te reguły na ACCEPT, ale to chyba czasowo będzie nie groźne. e.
