Couldnt ping the inside lan network using VPN Client.

Lost & Found — Tue, 12 Mar 2019 06:46:04 GMT

Hi,

I configured VPN Client on cisco asa and it's now connecting but I encountered some issues.

1. I can't ping the inside lan of our network (servers,host etc).

2. I can pint the inside interface of ASA 10.1.1.1.

please see the atttache file.

thanks

Hi, >> Are you able to ping

Hi,

>> Are you able to ping the server from ASA?

command: ping <inside-interface-name> <server-IP>

>> Can you check if you have any ACL that might block the traffic.

>> Is there any NAT for this traffic? If yes then ensure you have ICMP inspection enabled

command: fixup protocol icmp

>> In case you still face the issue try to check if the traffic is actually leaving the ASA or not. Use captures to check this:

command:

cap capi interface <inside-interface-name> match icmp host <source-ip> <destination-ip>

To view:

show cap capi

To delete:

no cap capi

Share your findings.

Thanks,

Hi, From the captures we can

Rishabh Seth — Tue, 20 Oct 2015 07:49:35 GMT

Hi,

From the captures we can see that the traffic is leaving the ASA and there is no replies from 10.34.49.1 device.

Probably the device is not configured to reply to ping or there is some firewall on the device which is blocking it.

Also check if there is any other device that might block the traffic.

From ASA perspective you are permitting all the traffic.

Share your findings.

Thanks,

R.Seth

Hi,I have configure firepower

Lost & Found — Tue, 20 Oct 2015 08:26:35 GMT

Hi,

I have configure firepower and the following command.

access-list ACL_ANY extended permit ip any anyclass-map SFR
match access-list ACL_ANY
class-map inspection_default
match default-inspection-traffic

class SFR
sfr fail-close

ive tried to remove the command but its still the same

I think i already permit all address on out acl.

access-list outside extended permit ip any 10.34.48.0 255.255.240.0
