[c-nsp] NAT and PAT on ASA

[Ryan West]

Kiran,

That's right.  If you run into issues trying to pass SIP through your firewall, you may need to look at the default service policy.  There are some protocol inspection rules enabled by default that might affect the passing of SIP traffic.

Hey Ryan,

That seems to be working, thanks. So if I want to allow more ports we do
it the same way right?

access-list myaccesslist ext permit tcp any host 58.66.76.88 eq SIP
access-list myaccesslist ext permit upd any host 58.66.76.88 eq SIP

Thanks,
Kiran

Guys,

 

I am new to the ASA world, I have a bunch of external IP's from the ISP
and I have an inside host that I want to access externally. How do I
translate an inside ip (192.168.0.100) to an outside address
(58.66.76.88) on the ASA? I should be able to ping and www from outside
world to my inside host. Please let me know how to accomplish this.

 

Many thanks,

K
