Padekite pakurti Linux Router (isspresta)

#2

Labai reikia pasharinti neta per Linux su windows Xp kompu. Pasikuriau DHCP serveri, viskas veikia, IP ishduoda. Bet niekaip negaliu padaryti kad routintu neta. Pas mane linuxe toks config: eth0 - tiesiog network korta per kuria prisijungiu prie neto per pppoe. ppp0 - mano internet connection eth1 - lan’as. IP: 10.0.0.1, Netmask 255.255.255.0, Gateway 10.0.0.1. Mano /etc/sysconfig/iptables

/proc/sys/net/ipv4/ip_forward viskas teisingai, parashyta 1. Su networkingu dar esu visishkai zhalias. Reikia pagalbos.

#3

bl banga ishkraipe configa, nu tikiuosi suprasite Šypsena

#4

echo “1” > /proc/sys/net/ipv4/ip_forward IPTABLES=/sbin/iptables EXTIF=" eth0" INTIF="eth1¨ $IPTABLES -P INPUT ACCEPT $IPTABLES -F INPUT $IPTABLES -P OUTPUT ACCEPT $IPTABLES -F OUTPUT $IPTABLES -P FORWARD DROP $IPTABLES -F FORWARD $IPTABLES -t nat -F $IPTABLES -A FORWARD -i $EXTIF -o $INTIF -m state --state ESTABLISHED,RELATED -j ACCEPT $IPTABLES -A FORWARD -i $INTIF -o $EXTIF -j ACCEPT $IPTABLES -t nat -A POSTROUTING -o $EXTIF -j MASQUERADE Cia jei pastovaus isorinio IP neturi. O ta *bliamba*svta kur virsuje tai istrink. baisu ziureti.

#5

padariau kaip tu sakiai /dev/null, tada mano /etc/sysconfig/iptables atrodo taip:

tachiau vistiek winXP neto nera… kas gali buti netaip?

#6

Pradziai tai, kad jokiai tinklushkei nereik nurodyt gateway. Uzdek INPUT ir OUTPUT i ACCEPT , o pac routinimas vyxta su POSTROUTING ish ppp0 i eth1 … tixliai cmd neacimenu.

#7

bandziau ir eth0 pakeisti i ppp0, vistiek tas pats… gal reikia kur nors add route padaryti?

#8

tai ka daugiau ideju nera?

#9

nu pradziai sakau: INPUT, OUTPUT, FORWARD i ACCEPT sustatyk, o paskui kazkas tokio: iptables -t nat -A POSTROUTING -i ppp0 -o eth1 -j MASQUERADE … nu kazkas tokio Cha cha tau duota pavyzdziu, be to turi manuala - imk ir bandyk.

#10

gal atsirastu jei padarytum ifconfig route iptables -L Ir windowsuose XP ipconfig /all ping 10.0.0.1 ping delfi.lt

#11

o kaip turi atrodyt jeigu kompas turi isorini IP’a? (eth0: pc - inet; eth1: pc - pc) aciu.

#12

$IPTABLES -t nat -A POSTROUTING -o $EXTIF -j MASQUERADE keiciasi i $IPTABLES -t nat -A POSTROUTING -o $EXTIF -j SNAT --to-source ISORINIS_IP

Vienzo susitvarkyk savo DHCP, kad duotu normalius DNS

#17

Mano /etc/dhcpd.conf parashyta: option nis-domain “domain.org”; option domain-name “domain.org”; option domain-name-servers 10.0.0.1; Tipo ash su tais DNS visai zhalias dar, gal galite padeti sutvarkyti man ta DNS? Va kiek zhinau ish mano isp saito: DSL settings * Primary DNS: 4.2.2.1 * Secondary DNS: 4.2.2.2 * Domain: dsl.verizon.net * Network protocol used: TCP/IP Beje dar turiu shitame kompe Windoes 2003 server instalines ir jis viska normaliai routina. Gal ish ten kokiu settings paimti?
