You are in over your head here. Again:

... this is not the place to get UFW support. Andy gave you a good
(mostly good :) ) answer which you do not seem to have enough
experience (as a Unix/Linux user) to understand.
The "$string" construct is a sh(1) shell variable. In Netfilter
terms, it is common to refer to the *ext*ernal *I*nter*f*ace as a
shell variable; "ext" for "external", "_" for space, and "IF" for
"interface".
In order to benefit from help on this list, you will need to be able
to deal in such abstractions. It is not possible to give you literal
"type this and it will work" instructions.
You'll definitely need more experience to be able to run the proxy
server you're hoping to use. I recommend that you concentrate on
learning basic user skills before trying complex system
administration tasks.
Good luck.
