Ello all once again. So sorry for the 4 month vacation from the forums. School has been busy but all in all i have good news about my schooling. They accepted my proposal for a new network engineering program and here is what is on it thus far. there will be more added. I wrote this up for them and they said they loved my choice of classes. They voted me onto student council and we went from there:
Server configuration and administration.
Network Operating Systems including Linux(Finally)
Business Law and security ethics
Certified Ethical Hacker certification.
Network monitoring and documentation
Telecom cabling and wiring for physical hardware.
Scripting and programing
CCNA and CCNP
Wireless networks and communications
Disaster recovery and prevention
Data center administration including cooling, UPS, ROI, NAS
So im excited BUT lets get to the meat of the subject.. I have built a hardware FW using SmoothWall. They are having a hard time answering my question. They are basically telling me that what i want to do is not recomended,Well to me i need to know how to do this so i can use it for future use. Apparently SW uses a linux program that i have never heard of called "Ip Tables" To me an IP table is like a routing table. But i guess in the *nix world its different.
My ISP blocks certain common ports on there end so that a household user cant use them for business purposes unless they buy a business line. I need to learn how to change the port in IP tables from port 45 (just an example) to port 43.. SW for some reason will not allow me to change my port numbers from port 45 to 43.
My isp blocks SSH and other protocol ports that i need open for various reasons. I wish they didnt but even if i had port forwarding it would still block it because i take it that the FTP server on the other end by default uses port 21 and if i try using port 8080, the server at the other end would have to know that port 8080 is being used for FTP.
Point is i own my own servers and i have them set up on diff ports than the default and i need to change the default values in IP tables to the same as the servers...
I know this is a very interesting let alone complicated question but some good advice would be nice. Also, is there a book about IP tables. I need one that is easy to understand..
Thanx in advance (TIA)
