I have CISCO PIX 515E. My DSL modem -> firewall -> router -> computers.
That's all i have, no other device. Now, can u show me what command I
should use to permit incoming traffic that originates from internal
network???
For now, i just use this method. Is there any security risk involves in
this method?
I never setup DNS server before and have very little knowledge on DNS, so
I don't want to use internal DNS for now, but I'll learn more about it.
For know, I just want to get this problem solves. Thank you for all you
help.
