Access rule for SMTP

sonitadmin · ‎10-24-2007

Client just switched over to using Postini for spam filtering. I need to add a rule on a Pix 501 to allow smtp from an IP range of 61.14.0.0-61.14.17.255. When I try to enter the range it doesn't recognize it. Could someone explain to me how to assing the range.

Thanks!

You can do it like this...

access-list outside_access_in permit tcp 61.14.0.0 255.255.240.0 host mail.server eq 25

access-list outside_access_in permit tcp 61.14.16.0 255.255.255.0 host mail.server eq 25

access-list outside_access_in permit tcp 61.14.17.0 255.255.255.0 host mail.server eq 25

61.14.0.0 255.255.240.0 = 61.14.0.0 - 61.14.15.255

will this work?

access-list outside_in permit tcp 61.14.0.0 255.255.240.0 host x.x.x.x eq smtp

Yes. 61.14.0.0/20 will include 61.14.0.0/24 - 61.14.15.0/24. This is 16 Class C's.
