This is going to be a simple NAT query but I can't seem to get my heard around the ASA/IOS NAT syntax (I'm a Cisco noob) so apologies in advance.
I have an ASA 5510 with two interfaces configured (outside addresses omitted):
Outside_DSL: <outside address>/29
Basically I want to NAT inside traffic to the outside address. I thought the following command would do this:
static (inside, outside_dsl) <outside_address> 10.6.0.0 netmask 255.255.0.0 0 0
I was wrong - I get an error "global address overlaps with mask".
I'm pretty sure this is relating to a gap in my Cisco knowledge so any help would be much appreciated.
