Presmerovani portu pres Firehol

[parm]

Prosim o radu. Mam Ubuntu jako router pripojeny na net za nimz mam stanice s WIN XP. Routovani resim pres firehol. Potreboval bych poradit, jak mam presmerovat port 3389 a 3350 na stanici s IP 192.168.1.52 pres forehol, abych mohl pouzivat vzdaleno plochu a jeste jine aplikace bezicich na XP z venku.

Vypis firehol.conf:

# $Id: client-all.conf,v 1.2 2002/12/31 15:44:34 ktsaou Exp $
#
# This configuration file will allow all requests originating from the
# local machine to be send through all network interfaces.
#
# No requests are allowed to come from the network. The host will be
# completely stealthed! It will not respond to anything, and it will
# not be pingable, although it will be able to originate anything
# (even pings to other hosts).

version 5

# Accept all client traffic on any interface
# interface any world
# client all accept

Zkousel jsem pridat routovani primo pres iptables
        iptables -t nat -A PREROUTING -i eth0 -p tcp -d ve.rejna.ad.resa --dport 3389 -j DNAT --to 192.168.1.52:3389
        iptables -t nat -A PREROUTING -i eth0 -p tcp -d ve.rejna.ad.resa --dport 3050 -j DNAT --to 192.168.1.52:3050

taky jsem zkousel

nat to-destination 192.168.1.52 proto tcp dport 3389
nat to-destination 192.168.1.52 proto tcp dport 3050

firehol sice restartuje bez problemu, vzdalena sprava ovsem nefunguje. Nevim jestli je nutne jeste neco nekde nastavit. Diky za pomoc.

Ty posledni radky by mely fungovat, zkuste kdyztak misto nat to-destination pouzit prikaz dnat. Umi forwardovat libovolny port do vnitrni site, a to klidne i na jiny port cilove stanice. Videl bych to asi takhle:

Kód: [Vybrat]

dnat to 192.168.1.52:3389 inface eth0 proto tcp dport 3389
dnat to 192.168.1.52:3050 inface eth0 proto tcp dport 3050Pri pokusu o spojeni zvenku si zkuste na routeru otevrit log prikazem

Kód: [Vybrat]

tail -f /var/log/kern.loga sledujte, co se deje.

Vypis z logu:
Dec 29 10:35:11 MPM kernel: [ 2317.517131] 'PASS-unknown:'IN=eth0 OUT=eth1 SRC=xxx.xxx.xxx.xxx DST=192.168.1.52 LEN=48 TOS=0x00 PREC=0x00 TTL=111 ID=1615 DF PROTO=TCP SPT=63819 DPT=3389 WINDOW=65535 RES=0x00 SYN URGP=0

z toho usuzuji, ze k presmerovani portu patrne dojde, ale spojeni mezi Windows se nenavaze. Napada Vas jeste neco? Patrne, tam budu muset zajet a podivat se na to na miste.
