Try "isakmp nat-traversal"
01-03-2007 08:08 AM
Strange thing...this config really works great from home with ADSL and Fiber. When i try from work (leased 100m/bit) i cannot not reach anything on Lan side. What could this depend on?
Cheers!
01-04-2007 01:23 AM
Use nat-traversal and make sure UDP 500, 4500 and 10000; as well as ESP (IP 50) and ICMP are permitted on the ISP.
Also, check the SetMTU utiliy of the Cisco VPN Client and set the MTU to 1300 or below.
Rate if this helped.

Daniel

Thanks for the command!
More issues found. We have a webserver inside (195.30.30.3) that should be reachable from internet. The outside webserver from internet has adress xxx.xxx.xxx.90 and should make a port forward to 195.30.30.3
If i change Outside ip of the pix to xxx.xxx.xxx.90 instead of 82 that my isp suggested i get it to work but then the VPN funtion is not working anymore. Please help and thank you again!

You should keep the Interface IP clear of anything else, as you have enough IPs from the ISP, and note that the XXX.XXX.XXX.82 is used by the interface, by the NAT and static (not a good overlap).
Use instead:
ip address outside XXX.XXX.XXX.82 255.255.255.240
global (outside) 1 XXX.XXX.XXX.83-XXX.XXX.XXX.89 netmask 255.255.255.240
static (inside,outside) XXX.XXX.XXX.90 195.30.30.3 netmask 255.255.255.255

Hi,
All is done, except that you will need to remove the old line:
static (inside,outside) tcp interface www 195.30.30.3 www netmask 255.255.255.255 0 0
From now one, the http server will be visible from the internet with the xx.xx.xx.90 IP.
Please rate if this helped.
Regards,
Daniel
01-25-2007 03:16 AM
Ok, thank Daniel! I will remove the line. The users complain about random access to internet www, pop3. Some users can connect while some can?t. This "feature" walks around and next morning a person who could not use internet now can use it?! With the old firewall this was not a problem.

you may need to clear xlate. You can remove the nat configs, but if youd ont clear it from the transaltion table, it wont work correctly
02-07-2007 05:06 AM
Hello!
I found out why the connection was unsteady. User license was restricted ti 10 user. Iahve now upgraded the licens. So now it should work great but no. Now i dont get VPN or portforward to work...please look at config.
Cheers!
