destination unavailable W/ vpn. All other net destination o.k.
 
(posting again because I don't see the original).

Hi all. I usually google my problem before I bother others with them, and this is probably on it's 4th day of trying to debug, and I simply can't take it anymore (no hair left). Also, I'm fairly new to this, so I must apoligize ahead of time, if this is a n00b thing (and I hope it is).

A new install of Mandriva (2007.0). Everything works great.

I've installed a ci$co VPN client (and am using the profile supplied by my work). When I start VPN, I get a tunnel, I'm assigned a client address IP of 10.1.15.*, and I can see the server address,

ie;
Code:

Your VPN connection is secure.
VPN tunnel information.
Client address: 10.1.15.6
Server address: 64.128.24.7
Encryption: 168-bit 3-DES
Authentication: HMAC-MD5
IP Compression: None
NAT passthrough is active on port UDP 10000
Local LAN Access is disabled

but when I try to ping anyone in that same area 10.1.15.*, I get

" From 10.1.15.6 icmp_seq=1 Destination Host Unreachable "

Now, this is ONLY in that area. I can still go everywhere else on the internet, just not in this group (I know there are multiple systems in this group).

Is this a firewall coniguration this? A NAT configuration thing? To my knowledge, I have not configured ANYTHING on the new install yet (its' all default, so firewall, etc is default).


Here are my goodies;

A look into my resolv.conf yeilds; (why the redundant nameserver?)

PHP Code:

nameserver 192.168.0.1
