+===== A basic script for handling ACLs of your Cisco Catalyst =====
 A handy script //( [[http://tuttodebian.blogspot.com/|taken from this site]] )// to keep the ACLs of our Cisco Catalyst 3560 in separate files, so as be able to edit them without connecting to the device and finally update them on the switch by using a perl script like this:

+option voip-tftp-server code 150 = ip-address;
+option voip-tftp-server 192.168.134.192;

+This should likely work for you as well, just make sure you replace the IP for “voip-tftp-server” with the address to your core phone server.  Hopefully the next time someone hits google looking for “option code 150 cisco phone” the clear answer isn’t so hard to find.

+</code>
+In fact, if you don’t define the clock rate command into the atm interface, the IOS set to 2600000 this parameter. To force it, use the command ‘clock rate aal5′; in my case I use the command ‘clock rate aal5 7000000′.

+===== 1:1 NAT (not Cisco NAT) example =====
+<code>
+! WAN interface
+interface FastEthernet0/0.457
+ encapsulation dot1Q 457
+ ip address 10.66.175.21 255.255.240.0
+ ip nat outside
+ ! PPPoE ip tcp adjust-mss 1412
+!
+! LAN interface
+interface FastEthernet0/1
+ ip address 192.168.156.1 255.255.255.0
+ ip nat inside
+!
+! Redirect 0.0.0.0 --> 10.66.175.21 --> 192.168.156.2
+ip nat inside source static 192.168.156.2 10.66.175.21
+</code>
+<note tip>With this rule ''ip nat inside source static 192.168.156.2 10.66.175.21'' it's done DNAT/SNAT (portforwarding as well as source NAT). **If things are not working as they should you might have b0rken IOS firmware on Cisco router!**</note>
+==== Cisco NAT ====
+<code>
+ip nat pool NAT 10.252.162.2 10.252.162.2 netmask 255.255.255.252
+ip nat inside source list 10 pool NAT overload
+access-list 10 permit 10.52.4.0 0.0.0.255
