[Sunhelp] Ultra5 as Internet gateway via modem ...

[Martin]

Hello Sunhelpers, ;)

Since I am rather new to Solaris I have some probably newbie questions...

I have a private network with some UNIX and Linux machines ... 
Right now I have configured the Linux PC as a Internet Gateway using ipchains
... ;)

Now my questions ... how can I configure Solaris to establish a ppp modem link
to my ISP and to get it act as Internet gateway, since I want to replace the PC
with it ..;)
I use on the linux box wvdial .... is there something similar ..?
I have a standard 56k V.90 external modem attached to the PC ... can I use it
..? 
If yes, how ... ? 

And how do I configure it for ip-masquerading and forwarding ... ? (IPchains ..?)

Please help me to get rid of the intel PC crap ...!!! ;)

I have one PC(Linux), 1 sgi Indigo2, 1 Sun Ultra5 360 and an Apple Powerbook G3
500 ... which then should have access to the internet via the Sun ... 

Second issue ... I have a Standard PC Hadrdisk Drive (IBM 5400rpm IDE )... 
Can I build it into the Ultra5 ... ? I'd like to know how ..?
And how to make it useable for Solaris (Formatting ...) 

ANY HELP is greatle appreciated .... it would be probably enough just to point
me to the right url's where I can get the information. ;)

Thanks in advance ..
