Trying to do a workaround for a SQL/application related problem. Per customer's security requirements, they're only using a single source IP for a single destination IP. The SQL/app problem is that while there are multiple connections from the same source IP, but with diferent source ports, the SQL/app end rejects more than one user when a query is issued. So I thought we could just NAT that single IP out to a pool and that would allow the destination to see multiple source IP's. Unfortunately, I haven't been able to get it to work yet, but then again, I haven't had to do a nat poll in a very long time. Here's what I've got:
int tunnel 8
ip nat inside
int vlan 10
ip addr 172.1.1.1
ip nat outside
ip route 10.22.78.0 255.255.255.0 172.1.1.2
ip nat pool Cust 10.22.78.10 10.22.78.100 netmask 255.255.255.0
ip nat outside source list Cust_out pool Cust add-route
access-list extended Cust_out
permit ip host 192.168.1.1 any
We also have another static NAT for the destination IP:
ip nat inside source static 10.22.80.53 172.22.80.53
VLAN10 is a LAN interface ni a DMZ.
