Will the VPN go down

[zaheer]

Hi ,

I have a site to site VPN and VPN clients

and for VPN traffic i got no nat and sysopt cpnnection permit-ipsec.

I want to configure port based access-list for the vpn client for ssh access to one of my vpn clients to a machine onside my LAn network.

if I remove the sysopt connection permit-ipsec will my existing VPN branch tunnel go down.

and can I use named access-list for the vpn client so i can get the ssh access ?

I m using PIX 515 E with IOS 6.3

zaheer, you can remove sysopt conn permit-ipsec and write the access list into the outside interface.

no sysopt conn permit-ipsec

access-list outside_access_in permit tcp host host eq 22

access-group outside_access_in in interface outside

As far as it taking the vpn down temporarily, I tested this on an ASA and the vpn remained up after I removed the sysopt command.

No problem, hope it helps.

Why all the 2 ratings?

Hi Adam,

Just one more question before i try it.

I have got VPN group for my VPN clients with split-tunneling.

and each vpn group has an access-list.

Also i have an access-list for my outside to inside traffic.

So will i have to merge all me VPN group ACLs to the outside to inside ALCs ?

What do your split tunnel acl's look like?

[zaheer]

the vpngroup and the ACL for that is as follows

access-list acl_test permit tcp host 10.0.0.55 host 192.168.x.x eq ssh

vpngroup test address-pool abc

vpngroup test split-tunnel acl_test

vpngroup test idle-time 1800

vpngroup test password ********

10.0.0.55 is my VPN client

and my server is in 192.168.x.x range

[acomiskey]

access-list acl_test permit ip 192.168.0.0 255.255.0.0 10.0.0.0 255.255.255.0

no sysopt conn permit-ipsec

access-list outside_access_in permit tcp host 10.0.0.55 host 192.168.x.x eq 22

access-group outside_access_in in interface outside

so its gooing to be like my acl_test is my intresting traffic for VPN and acl outside_access_in is for the ssh

thank you Adam.
