Unable to use RDP through ASA

cosguy699
Level 1
Level 1

We just switched to a 5510 from a PIX 515 last evening, and the only things that are not working are any services from the outside to the inside.  Example: I am unable to connect to a RDP server on the inside from the outside.  I've been looking at the config for the past five hours, but am unable to see my mistake.  Running 8.2(1)   People on the inside are able to get out.  Thanks for any suggestions.

Hi Dale,

Pretty straight config. I am not sure why you need the entry.. :

static (Outside,inside) 10.10.8.10 1.1.1.4 netmask 255.255.255.255

Can you remove this and try RDP?

Thx

MS

MS,

I removed the entry, but still does not work.  That line was my static nat to the inside server  x.x.x.4

Thanks

I see everything is fine with your configuration, would you mind, doing a write mem first and then reloading the ASA and the ISP device once, you might just need to clear the arp cache on the devices after replacing the firewalls.

Hope this helps,

Thanks,

Varun

Hi Varun,

I did everything you suggested last evening EXCEPT for reloading the ISP device.  I'll do that now and report back.  As od now, before ISP reload, I am able to ASDM to the ASA from the outside.

Thanks

Sure let me know how it goes.

-Varun

Thanks,
Varun Rao

Varun,

I reloaded the ISP device, but still was not working.  I then looked at my statics and saw that I had reversed the direction. ie:  should have been static (inside,outside) x.x.x.4 10.10.8.10 NOT static (outside,inside) 10.10.8.10 x.x.x.4

Everything is working fine.  Thanks for you assistance.
