multiple networks access through remote vpn

Hi guys!

I have remote vpn configured on my ASA 8.6.1 and it works fine but i want to access to multiple networks which are situated behind inside interface of ASA.

Vlan 3(192.168.3.0/24) <=Cat 3750=>  Inside int ASA (192.168.10.0/24) == Outside interface <== remote vpn access==> VPN CLient (network 192.168.100.0/24)

I tried to add new nat rule, but it doesnt works.

Re: multiple networks access through remote vpn

The new network has to be included also in your Split-Tiunnel-ACL:

access-list split_tunnel remark VLAN3

access-list split_tunnel standard permit 192.168.3.0 255.255.255.0

And NAT-Excemption has to be extended for this network:

object network VLAN3

  subnet 192.168.3.0 255.255.255.0

nat (inside,outside) source static VLAN3 VLAN3 destination static VPN-POOL VPN-POOL no-proxy-arp route-lookup description NAT-Excempt for VPN

It doesnt work

"It doesn't work" is not really a problem-description ... ;-)

What's your actual config and how did you test it?

This is the whole config. I made a mistake in first scheme when i said about vlan 3. I tried to have routing into vlan MGMT but now i dont have it.

Also i have route on my cat3750: ip route 192.168.100.0 255.255.255.0 192.168.10.252

Re: multiple networks access through remote vpn

The mentioned config is still missing (split-tunnel and NAT-excemption for the additional network). And your ASA needs a static route for the network behind the 3750.
