Neshto nemozhah da razbera iskash i dvetete mrezhi da
sa s relani IP-ta, rutera ti ima dve mrezhovi karti, a wryzkata
kam internet kakva ti e ? (ppp??) Ako predpolozhim che imash
ppp wrazk kam inet mozhe da izpolzvcash nestho takova

----- script start ----
#!/bin/sh
#
# /etc/rc.d/rc.inet1 (slack7) slightly modified by _GF_
#

echo "Configuring lo interface...."
/sbin/ifconfig lo 127.0.0.1
/sbin/route add -net 127.0.0.0 netmask 255.0.0.0 lo

IPADDR="212.124.68.2"                # Tova ti e tvoita mrezhova karta
NETMASK="255.255.255.240"    # 16 mashini
NETWORK="212.124.68.0"
BROADCAST="212.124.68.15"

IPADDR1="212.124.68.17"            # Tova ti kartata kam game club-a
NETMASK1="255.255.255.240"    # 16 mashini
NETWORK1="212.124.68.16"
BROADCAST1="212.124.68.31"

echo "Configuring eth0 as ${IPADDR}..."
/sbin/ifconfig eth0 ${IPADDR} broadcast ${BROADCAST} netmask ${NETMASK}

echo "Configuring eth1 as ${IPADDR1}..."
/sbin/ifconfig eth1 ${IPADDR1} broadcast ${BROADCAST1} netmask ${NETMASK1}
----- script start ----

Ako izpolzvash ppp i tovia provider ti dava adres primer 212.124.68.1
to ppp-to priconecia shte dobavi waw routing-a

/sbin/route add default gw 212.124.68.1 netmask 0.0.0.0

A ppp device shte e s IP  212.124.68.1

Na mashinite w tvoia club gateway-a triabva da im e IP-to na parvata mrezhova
karta.
Na mashinite w game-club-a gateway-a triabva da im e IP-to na wtorata mrezhova
karta.

Po tozi nachin i dvete mrezhi sa s realni IP-ta, wizhdat se edna druga i dvete
ima wrazka
s internet.

Ako iskash IP-tata na game club-a da sa po-sredata na tvoite IP-ta toest ti
imash
212.124.68.1/24

iskash game club-a da e 212.124.68.16/28

mislia che triabva da slozhish na parvata mrezhova karta oshte edno ip
