[Solved] FreeBSD internet, Windows Domain - Page 2

post #11 of 17
Can you ping Google by IP address?
Code:
ping 173.194.41.65

If so, then problem is with your nameservers then. in your resolv.conf you have:
Code:
nameserver      172.21.3.10
That nameserver only has internal domain names on it. So you need to add some name servers that hold external domain names.

eg
Code:
nameserver      172.21.3.10
nameserver      8.8.8.8
nameserver      8.8.4.4

(this will add Google DNS)

Now I'm not saying that you should use Google DNS (there's plenty of good reasons why you shouldn't), but it's just an example of hose the file should be laid out. Your Windows boxes should have more than one name server listed as well (the DNS suffix search list field when you type ipconfig /all in cmd.exe)



If you cannot ping Google by IP then the issue is with your routing.

Nothing
Code:
ping -c 3 173.194.41.65
PING 173.194.41.65 (173.194.41.65): 56 data bytes

--- 173.194.41.65 ping statistics ---
3 packets transmitted, 0 packets received, 100.0% packet loss

I already had google's public dns for testing confused.gif
Code:
cat /etc/resolv.conf
domain  domain.com
nameserver      172.21.3.10
nameserver      8.8.8.8

Trace route trying to find something...
Code:
 1  172.21.3.250 (172.21.3.250)  4.653 ms  0.358 ms  0.353 ms
 2  * * *
 3  * * *
 4  * * *
 5  * * *
 6  * * *
 7  * * *
 8  * * *
 9  * * *
I don't get it, isn't it supposed to be simple? You select your gateway and that's it mad.gif. I don't even see my ISA server blocking anything, is like the packages are not going anywhere.

It's probably routing then. I'm rubbish at that side of things though (it's the one bit of Unix / Linux networking that I've never got my head around).

Pick a spot and start there. first try to ping the router its connected to. if you dont get a reply then you are broken right away. fix that then try to ping the next item. keep going till you get internet. i personally would use nameserver 8.8.8.8 as your primary. also make sure you dont have network manager running sometimes it like to over write crap even if you set it manually via the cli.

 

 

rememer start at the begenning and use basic steps. is the cable connected. is the interface up. does the interface have a route a gateway an ip address subnet mask broadcast address dns stuff like that. and then ping your way out.

 

if you can install MTR id install that and use it as well. i like it better then just standard ping test and traceroutes. its like a combo of the two. its good for showing ups and ping with packet lost. shows current. average best and worst.

See if you can ping your router. If that succeeds then try to ping your firewall. Have you checked the firewall to make sure it's not blocking the traffic from the new server to the world or the returning traffic?

Also is your router and firewall set to respond to and allow icmp requests through?

Hello again guys, so after a long time I finally found my problem. After checking every single configuration I did on the FreeBSD server and failing I decided to focus on windows stuff, and today I noticed the http_proxy variable I configured wouldn't work for ISA Server, found a something in google that said: "Call your IT guy to enable Basic Authentication in ISA server". I hate myself a little bit for not knowing that.

And that was it, my requests are finally getting out of my lan.
  • Open ISA Server management
  • Under Configuration - Networks
  • Right click the Internet access rule, specifically Internal network
  • There go to Web Proxy and click Authentication
  • And enable Basic authentication which is the one passed by http_proxy

Here is an image of the configuration in ISA

So i was right all along, it was an authentication issue smile.gif

I knew this would be the case because when I used to bypass corporate security at work I would tunnel SSH through the ISA https proxy by authentication using ntlmaps, which is similar to cntlm. However its good to know you can switch to basic authentication as well, if you have the privilege of being the ISA admin wink.gif
