+====== Howto Setup Linux as router for ppp dial up (PSTN/ISDN) connections ======
+Quelle((http://www.cyberciti.biz/tips/linux-as-router-for-ppp-pstnisdn-connections.html))
+This step by step howto will help you to setup Linux as router only in two (2) minutes. I'm assuming that your setup is as follows:
+(A) You are using RedHat Linux, FC linux/Debian Linux (this should work with ALL Other distros as well :D )
+(B) ppp0 is internet interface (connected to Modem for example) and eth0 connected to your internal lan (connected to your HUB/Switch for example)
+  * My Linux  --> eth0
+  * Box      --> ppp0 (comes up when you dial up into ISP)
+Step # 1 Turn on ip forwarding in kernel
+) Open linux kernel configuration file:
+<code> # vi /etc/sysctl.conf</code>
+) Add/modify following line:
+ net.ipv4.ip_forward = 1
+Step # 2 Restart network
+<code># /etc/init.d/network restart</code>
+OR
+<code> # service network restart</code>
+(Note first dial to ISP using wvdial or similar program )
+Step # 3 Setup IP forwarding and Masquerading (to act as router), you need to use NAT option of iptables as follows:
+<code> # iptables --table nat --append POSTROUTING --out-interface ppp0 -j MASQUERADE
+ # iptables --append FORWARD --in-interface eth0 -j ACCEPT</code>
+Step # 4 You are done! Test it with ping or dig:
+<code>
+ # ping your-isp.com
+ # dig www.nixcraft.com
+ # dig yahoo.com
+</code>
+Step # 5 Point all client to your eth0 IP address as Router/Gateway.
+Step # 6 Put code described in step # 3 to script and call it from /etc/rc.local
