With some great help of unclerico on this forum I have succesfully running a Cisco PIX 520 where I can connect to with the Cisco VPN Client. Now I like to setup a new internal subnet where some slected user can connect to. The new internal subnet is in an other range than I allready use.

Do somebody know how to setup this?

This is my configuration now:

Code:
PIX Version 6.3(5)145
interface ethernet0 auto
interface ethernet1 auto
nameif ethernet0 outside security0
nameif ethernet1 inside security100
hostname pix
domain-name domain.net
fixup protocol dns maximum-length 512
fixup protocol ftp 21
fixup protocol h323 h225 1720
fixup protocol h323 ras 1718-1719
fixup protocol http 80
fixup protocol http 2222
fixup protocol rsh 514
fixup protocol rtsp 554
fixup protocol sip 5060
fixup protocol sip udp 5060
fixup protocol skinny 2000
fixup protocol smtp 25
fixup protocol smtp 2525
fixup protocol sqlnet 1521
fixup protocol tftp 69

On this moment we use as internal range 10.15.10.0/24 and VPN users will get a IP from the 10.15.11.0/24 range.

For the user it's wishful to use 10.15.12.0/28 as internal range with 10.15.12.1 as gateway and 10.15.12.15 as broadcast. It need to be possible that the user can reach this range with an IPSec VPN account from external locations.

Do somebody know how I can create this situation?

Any help on this subject is much appreciated. Thanks in advance!!
