My next problem where to find which firmsware to use. But after i solved this i changed internet provider from bredbandsbolaget to tele2, and now THAT is working, the DHCP problem.

My next problem is to set up a DMZ, but it seems like the manual is wrong, so when i follow the manual, it doesn't look as the picture in the manual

For firmware updates, you need to have an active SmartNet contract through Cisco. You can log onto Cisco using your SmartNet credentials, go to downloads and then security appliances. Look for the ASA and download both the latest ASA firmware and ASDM software (they usually go hand-in-hand).

For DMZ config, you should connect E2 to your DMZ. In other words, E0 is to the Internet, E1 to your LAN and E2 to your DMZ. I won't get into the actual configuration of the DMZ here as that is a whole separate, and lengthy, subject.

How to counfugre asa 5505 cisco Router

Use the Cisco ASDM or SDM software, that will give you an easy graphical interface to configure the ASA. One of them would have been shipped with the device.

Don't forget the ASA has to pre-configured, just a simple config. Have HTTPS enabled and telnet/SSH helps as well if you dont have a serial port or the console cable.

Cisco's website will give you quite a lot of info for free...

Cisco ASA 5505 Firmware

Yes, it is possible and Yes you have to purchase it from Cisco.
Sorry, that is how they make the big bucks.
Consider a service contract on the unit, then you can download the firmware much cheaper.

Upgrade firmware on a cisco ASA 5500 firewall

This is for the pixes, I haven't upgraded an asa yet...should be close or the same

* find latest version of code, these are usually *.bin files located on http://www.cisco.com/cgi-bin/tablebuild.pl/pix
* confirm the flash and RAM requirements of the PIX OS software versus what the PIX has (”sho ver”)
* make sure you have a backup of the old PIX OS and PDM to the tftp server (or at least confirm the software is there)
Note: You cannot back them up from the PIX, so you will need to download them and put them on the tftp server * put in a change control form
* once change controls confirms date/time do the upgrade:
wri mem*** only if you save your configs via tftp wri net conf t ca save all copy tftp://your tftp server ip/pix635.bin flash:imageskip this if you don't use pdm copy tftp://your tftp server ip/pdm-304.bin flash:pdm *** if this is a failover pair, upgrade the other pair reboot
