Hi Guys,
I'm struggling with my ASA config it's driving me nuts! Can you guys tell me what I'm missing? I'm new to ASAs.
I have Vlan 100 (inside) and Vlan 65 (Outside)
I'm trying to configure RDP and ping traffic from Vlan 100 to Vlan 65 One way.
If I connect 2 PCs on E0/0 and E0/1 they can happily ping the their own VLAN ip add 192.168.100.3 and 172.16.65.1
I've copied my config, please help Cisco Gurus
ASA Version 8.4(4)1

No one knows?

Hello JDM,
Dude is this a typo?
Vlan665
interface Ethernet0/1
description Vlan 65 A Network
switchport access vlan 65
!
Let me know,
Regards,
Julio
09-05-2012 02:30 PM
Hey Julio,
Yup Sorry, should be Vlan 65
Thanks
09-05-2012 02:32 PM
Hello,
Change it and let me know,
Also add the following command:
Fixup protocol icmp
and let me know what happens.
Rate all the helpful posts that is as importan as a thanks.

what does that command do?
I will give it a go and let you know thanks.
Just abit of background when I try to ping or RDP from vlan100 to vlan 65 I see nothing on the logging in ASDM. could it be routing?
Many Thanks
09-05-2012 02:48 PM
Hello,
Did you already changed the vlan number??
The fixup protocol ICMP will start inspecting on a stateful way the ICMP protocol so no need for ACL to allow the returning traffic.
Please provide me the ICMP source and destination Ip's
09-06-2012 12:26 AM
yes vlan changed to 65, added fixup protocol icmp
host 192.168.218.88 ping 172.16.65.100 PING:transmit failed. general failure
host 192.168.218.88 pinig 192.168.218.4 - Ping replies
host 172.16.65.100 ping 192.168.218.88 PING:transmit failed. general failure
host 172.16.65.100 ping 172.16.65.1 Ping replies
Again in logging I see no traffic hitting the firewall. I can see icmp traffic if it hits the VLAN IP Address on ASA
Many Thanks
09-06-2012 12:32 AM
Sorry my bad I do see messages in debugging level
172.16.65.100 ping 192.168.218.4 tear down icmp... etc
172.16.65.100 ping 192.168.218.88 : No translation group found for icmp src VLAN65: 172.16.65.100 dst INSIDE: 192.168.218.88 (type8, code0)
09-06-2012 09:09 AM
Hello JDM,
Please do the following:
access-list outside_in permit icmp any any
access-group outside_in in interface outside
packet-tracer input inside icmp 192.168.218.88 8 0 172.16.65.100
packet-tracer input outside 172.16.65.100 8 0 192.168.218.88
Paste the whole output of each of them,
Regards,
Julio
