LinkController without SNAT ?

Hi all.

 

I have a box BIG-IP LTM (with license both of LTM & LinkController ).

 

I have 2 ADSL as:

 

---------------- ------------------

 

- 203.162.0.x - - 210.245.0.y -

- 203.162.0.1 210.245.0.1 -

 

- F5 LTM -

 

- 172.16.1.x

 

---------------------------------------------------

 

|

 

ASA 5550

I have Vir 203.162.0.10 & Vir 210.245.0.10 for Inbound with SNAT. (Pool is server 's ip ASA). SNAT make BIG-IP choose correct gate-way to go out.

 

And the IP forwarding for ASA to outbound.

 

Default-gateway of BIG-IP is pool (203.162.0.1; 210.245.0.1) .

 

But I wonder that, SNAT make Sever can't collection information about Internet User (ip address).

 

1. Can I config LTM without SNAT in this situation ?

 

2. I need config LinkController for VPN site to site from Cisco Router800 (in Internet) to ASA5550. I wonder SNAT make ASA not understand Cisco Router 's ip add and can't make tunnel VPN.

 

Any body have the same problem?

 

Plz, help me.
