| Cisco 2811 static nat statements stopped working!
I checked my servers this morning and I had lost outside connectivity to my email and ftp servers. Checked public IP's from the outside and there is no connectivity. I have Internet and all other network traffic is normal.
I have 3 ip nat inside source static statements that direct traffic to my email, ftp and a Citrix gateway. None of these are working. No changes have been made to the router config. The Cisco 2811 router and switch have been restarted several times.
Anyone have any ideas on this issue? My email server is down and I am pressured to get this back up and running.
Thanks for your help! |

@cox.net | reply to jgh52 Running a tracert from the outside stops at our provider. I assume the last hop before the router.
Thanks for the response. |

@cox.net | reply to jgh52 Also the nat'd public IP's are resolved by my internal DNS servers. DNS appears to be working fine internally. |

@cox.net | reply to elnino It shows the inside global to inside local IPs and that looks good. Nothing in outside global to outside local.
Thanks, |
