I have a Cisco 5510 deployed and it's connected to a 1 Mbps leased internet line. I need to configure it for remote VPN users to access internal Exchange server and sync with email system. And they should be able to access LAn servers using the VPN. I have tried this several scenarios but still I didn't get access to to local LAN servers via VPN at any cost :( (it's connecting well and also can ping to the inside interface IP address only)
Any help would be highly appreciated.
Below is my config;
LAN is 192.168.134.0

Hello,
your NAT 0 access-list has wrong subnet mask for the vpn pool subnet and your vpn pool has 255.255.255.0
nat 0 acl has "192.168.166.0 255.255.255.128"
access-list inside_nat0_outbound extended permit ip 192.168.134.0 255.255.255.0 192.168.166.0 255.255.255.128
ip local pool primary-vpn-pool 192.168.166.1-192.168.166.100 mask 255.255.255.0
change the subnet mask on NAT 0 access-list to 255.255.255.0 and then check .

in the new config you have still not changed the subnet mask in the Nat0 access-list that i asked earlier.
09-10-2008 10:47 AM
changed mask to 255.255.255.0 it just now !!! but still no luck !
09-10-2008 10:33 AM
Do you see "hitcounts" increasing on access-list inside_nat0_outbound ?
check and post result of
show access-list inside_nat0_outbound
09-10-2008 10:43 AM
abc-fire(config)# show access-list inside_nat0_outbound
access-list inside_nat0_outbound; 1 elements

09-10-2008 10:51 AM
Your access-list still does not reflect the change , also why have you changed 192.168.134.0 's subnet mask to 255.255.255.128 ??
your access-list should look as following:
access-list inside_nat0_outbound line 1 extended permit ip 192.168.134.0 255.255.255.0 192.168.166.0 255.255.255.0
09-10-2008 11:00 AM
ok i have removed 128 subnets and now it's all coming with 255.255.255.0 mask !!
but still no luck ! :( but i can ping 192.168.134.125 which inside interface ...!!!
???
