We have the Pix 506 with IOS version 6.3(4)
We publish our inside https web server 10.12.1.50 port 443 to outside address X.X.X.2 port 443
And sometimes the publishing of our inside web server doesn't work.
Log message when publication works normally:
<166>Apr 21 2008 08:14:42: %PIX-6-302013: Built inbound TCP connection 235 for outside:220.127.116.11/52058 (18.104.22.168/52058) to inside:10.12.1.50/443 (x.x.x.2/443)
Log message when publishing doesn't work:
<166>Apr 21 2008 08:09:37: %PIX-6-302013: Built inbound TCP connection 566372 for outside:22.214.171.124/52874 (126.96.36.199/52874) to inside:10.12.1.50/443 (x.x.x.129/443)
Why the address (x.x.x.2/443) was changed to (x.x.x.129/443)? There is no address (x.x.x.129/443) in config file.
And, we can't understand where was error, because it is repaired only after three or four reboots of the pix and the web server.
Can you help me?
I shall be thankful to you for your aid.
