NAT FWSM context interface IP to a virtual IP address

[aravind.krishnan]

I am in confusion on whether static nat works for the diagram attached here with. Requesting your help to resolve it.

We have an FWSM and in that 7 context are configured. Each context has an Inside and outside interface. My requirement is that Outside interface of a particular context needs to be mapped to a virtual IP address. So that when traffic comes through Inside interface need to hit the virtual IP address and then it should translate to the real outiside Interface IP address.

I have configured static(outisde,inside) 30.30.30.1 20.20.20.1 netmask 255.255.255.255. But it didnt worked. I checked the Xlate table and this entry is not created there. So I tried static pat with UDP SNMP port. Even that didnt worked. I got an information that Interface IP address cannot be translated. There could be some confusion for the incoming traffic about the destination and where it have to send the packet.

Please help.

I forgot to add my questions in my earlier post.

1.If my requirement is possible, what are possible issues that can araise?

2.Will any of the connection that passes through context will be effected?

3.If it is effected, then is there any way that can be reduced?

I am using FWSM Version 3.2

Thanks,
