Sunt in criza de timp ...
Am urmatoarea problema
un linux cu iptables:
eth0 - 10.0.1.100
eth1 - 192.168.100.68
rth1:0 - 172.25.10.68
default gw 10.0.1.1
trebuie sa permit unui calc care vine prin eth0 cu adresa 10.254.3.50
sa acceseze niste servere oracle ( portul 1521 )si unul de web
(port 80 ).
++++++++
iptables -t nat -A PREROUTING -p tcp -d 10.0.1.10 -i eth0 --dport 81 -j
DNAT --to 192.168.100.111:80
iptables -t nat -A OUTPUT -p tcp -d 10.0.1.10 --dport 81 -j DNAT --to
192.168.100.111:80
iptables -t nat -A PREROUTING -p tcp -i eth0 -d 10.0.1.10 --dport 1521
-j DNAT --to 192.168.100.20:1521
iptables -t nat -A OUTPUT -p tcp -d 10.0.1.10 --dport 1521 -j DNAT --to
192.168.100.20:1521
+++++++++
Chain OUTPUT (policy ACCEPT 6 packets, 360 bytes)
pkts bytes target prot opt in out source
destination
0 0 DNAT tcp -- * * 0.0.0.0/0
10.0.1.10 tcp dpt:81 to:192.168.100.111:80
0 0 DNAT tcp -- * * 0.0.0.0/0
10.0.1.10 tcp dpt:1521 to:192.168.100.20:1521
++++++++++++
Serverele 192.168.100.111 si 192.168.100.20 au route manuale catre calc.
care face cerere ( raspunde la ping )
Daca dau telnet pe 10.0.1.100 port 81 ramane pe Trying si unable .
Imi scapa ceva ...
Multumesc !
