Hi all,

I am new to remoting.

I heard that binary formatted data will not work through firewall. And
soap formatted data will work

Can anyone tell me why is it so?

That is NOT true. I use binary formatting through a firewall all the time.

The confusion probably comes about because if you're using soap you're
probably doing it via HTTP and port 80. Port 80 is usually open on
firewalls. Most of the examples for using binary formatting use TCP on some
random port which probably isn't open on the firewall. You can use port 80
with binary formatting and TCP as long as you aren't interfering with IIS or
other uses of port 80. Or, you can open some other port on your firewall.

That depends. It is not always true.

SOME firewalls can be configured to block any data that is not plain text
over port 80. That is NOT the norm for companies though.

As long as you are using an open port you are usually ok. The biggest
problem I have seen is when people are using non-standard ports to host
their remoting applications. Host your remoting application in IIS, use
port 80 and you are almost always safe.
