Ok takze da sa to robit napr. cez ipmasqadm (kernel space) alebo portfwd
(userspace). ipmasqadm zere menej pamati a je integrovany do kernelu, portfwd
zvlada aj ftp a ide aj zvnutra maskarady (v kerneli to bude mozne az od 2.4),
ale na kazdy port sa zvlast forkne a bindne.
Obe najdes na freshmeate.

Pouzitie:
ipmasqadm portfw -a -P tcp -L morpheus.panorama.sth.ac.at 800 -R shurdeek ssh
(port 800 na morpheovi je presmerovany na moj notebook (ssh port))

/etc/portfwd.conf:
user nobody
group nobody
tcp {
	801
		/* vonkajsi interface routra */
		ftp-passive-mode-on 193.170.53.10
		/* vnutorny interface routra */
		ftp-active-mode-on 10.1.20.51
		/* kam sa to vlastne ma presmerovat */
		{ => 10.1.34.6:21 }
}

Analogovo pre UDP (aj ipmasqadm aj portfwd).

Okrem nich mam dojem ze su aj nejake dalsie, ale prakticke skusenosti nemam.
Spokojny som s oboma.

S pozdravom,
