IPSec VPN users cannot reach internal servers.

danielbowne
Level 1
Level 1

I am trying to setup an ASA 5505 for VPN access to a remote site.  When connected to VPN I can ping the internal interface(192.168.10.1) but no internal hosts.  Also internal hosts can ping the connected vpn users.  VPN users can also browser the internet.

It is not just ping but all services(http/https..etc).  What they heck am I doing wrong?

 

Any suggestions would be great!

 

Internal network: 192.168.10.0/24

VPN Pool 192.168.11.0/27

Hi,

 

r u using both vpn pool and internal lan with same subnet? if so please change it to a different segment.... create a no-nat for the traffic between vpn pool and internal lan subnet...... if you are restricting in access_list on outside interface.... then allow the vpn pool towards internal lan...

 

Regards

Karthik

miss type in notes:  Correct info > VPN Pool 192.168.11.0/27

Hi,

 

Allow in outside intrerface binded access-list for the traffic between your vpn subnet to local internal lan..... or you need to give sysopt connection permit vpn to skip the interface acl's filtering for vpn users....

 

Regards

Karthik

Is there a route on the router or layer 3 switch for the inside network that forwards 192.168.11.0 toward the ASA?
