We just moved from a
NAT router (Cisco 2621) to a PIX 520 firewall. Now when we send email to
EarthLink, we are being blocked with a:
"550 Dynamic IPs/open relays
blocked. Contact <[EMAIL PROTECTED]>."
message in the
logs.
The only difference that is
known between the NAT and PIX configuration is that traffic used to be shown as
coming from 199.44.118.253 using NAT. Under PIX iit is coming from
199.44.118.252.
Does anyone have any ideas? Is
there a change to IMail I should have made?
Thanks.
Hank
