Hi

my scenario is as follows

SERVER1 on lan (192.168.5.2/24)

|

|

CISCO-887 (192.168.5.4) with VPN server

|

INTERNET

VPN Cisco client on xp machine

My connection have public ip address assegned by ISP, after ppp login.

I've just configured (with Cisco Configuration Professional) the ADSL connection and VPN Server (Easy VPN).

All the PC on LAN surf internet and remote PC connect to VPN Cisco server via cisco VPN client.

But all remote PC after connection to Cisco VPN server don't ping SERVER1 in lan and therefore don't see SERVER1 and every other resource in LAN.

They can ping only router!!!

They are configured with Cisco VPN client (V5.0.007) with "Enabled Trasparent Tunnelling" and "IPSec over UDP NAT/PAT".

What is wrong in my attached configuration? (I've alspo tried to bind Virtual-Template1 both to unnambered Dialer0 and to Loopback0 but without luck)

Peraps ACL problem?

Hello,

Your pool of VPN addresses is overlapping with the interface vlan1.

Since proxy-arp is disabled on that interface, it will never work

2 solutions

1- Pool uses a different network than 192.168.5

2- Enable ip proxy-arp on interface vlan1

Cheers,

Olivier

saved me my men! stubled to this article by mistake! for me it was the Enable ip proxy-arp on interface vlan1
Now i m looking on making Split tunnel :) think its just an access list and apply it to isakm group....
