[c-nsp] NAT and PAT on ASA

[Oddiraju, Kiran @ London SMC]

Hi Ryan,

I have the below config in the protocol inspection rules, do you think
this is enough?

class-map inspection_default
 match default-inspection-traffic
!
!
policy-map type inspect dns preset_dns_map
 parameters
  message-length maximum 512
policy-map global_policy
 class inspection_default
  inspect dns preset_dns_map
  inspect ftp
  inspect h323 h225
  inspect h323 ras
  inspect rsh
  inspect rtsp
  inspect esmtp
  inspect sqlnet
  inspect skinny
  inspect sunrpc
  inspect xdmcp
  inspect sip
  inspect netbios
  inspect tftp
  inspect icmp
!


Many thanks,
Kiran

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
