Oracle Solaris as a small network router?

Question

Solaris

Good afternoon

Please tell me which way to dig in order to raise a small network router on Oracle Solaris 11. If everything was clear with Linux - raise a squid, raise iptables, raise dhcp, allow forwarding on some ports and open ports 3128 and 63 on the internal interface, then how to do this in Solaris is completely incomprehensible.
For example, when configuring dhcp, the DNSdmain option was misunderstood.
It is also not entirely clear how to explain to Solaris which of the interfaces is internal and which is external.
Well, another small question - how to allow Skype to work on client machines?

Sorry, so many questions in one thread. I really hope for help. Preferably with specific and simple examples, rather than references to documentation.

download.oracle.com/docs/cd/E19963-01/821-1453/gcvjj/index.html - the official manual (there is a lot written there, and it seems to be quite detailed). About dns you need to read on ISC, about squid - on squid-cache.org
Skype should work through a proxy.
