It may function, but is it REALLY secure?

The issue starts with keeping it up to date. Some of these open solutions support automatically updating. I dont think the PIX do.

True, it is a end of life product, but I wouldn't say its any less secures as not supported. Would I put it in a REAL production environment? probably not....


Upgraded my IOS to 12.4 advanced enterprise and I now have access to that command biggrin.gif

seems like everything working good.

Upgraded the IOS on my 1841, still cant do it with a port. May need to find more IOS versions and see.

Maybe the 1841 was discontinued for a reason? xD

I am glad to hear it works, I still was not able to find any documentation supporting it. Maybe I will visit my CCNA instructor and see if I can borrow a newer router for a bit.

Yeah I've tested SSH and logging into minecraft server and all goes well. I'll be hosting a FTP server soon for fellow CCNA students to "acquire" ios images for learning purposes thumb.gif

Heres the relevant commands (with ip nat inside/outside set to proper interfaces)
Code:
ip nat inside source list 100 interface FastEthernet0/0 overload
ip nat inside source static tcp 172.x.x.x 22 interface FastEthernet0/0 XportX
ip nat inside source static tcp 172.X.X.X 8142 interface FastEthernet0/0 XportX
ip nat inside source static tcp 172.X.X.X 22 interface FastEthernet0/0 XportX
!
access-list 100 permit ip 172.X.X.X 0.0.0.255 any

Keep me posted on the FTP server.

Thanks for helping me to learn something. This kind of brainstorming really helps to burn the findings into memory. As a new CCNA, I can use all the burning into mind I can get.

Yeah, I get where your coming from. I always love a challenge, especially when the words "Thats impossible!" are spoken biggrin.gif

I just finished my x4 Cisco precursor courses to the CCNA, ended up getting a free shot to take the CCNA and failed. redface.gif
Kinda sucks I'll have to fork out 300ish to retake it :/

I failed my first one too.

However, I didnt see it as a failure. Its those damn labs in that 320x240 pixel window.

Really taught me how to better document what I was working on with that stupid dry erase page thing. My proctor also only had the big fat dry erase markers.

I wrote all over the desk with the marker. Stupid proctor.

I know what you mean...I was all prepped and ready to take the CCNA, then they canceled due to "technical difficulty " . Ended up taking two weeks later and my study material had expired two days after I was originally suppose to take the CCNA...Needless to say going two weeks without studying at all didn't help
