When I do a what-is-my-ip it shows me one IP address. When I do a traceroute out to the internet, the first internet address I see is the same as the web browser results but one number lower....

There maybe a network-address-translator involved. I would not expect the address to be one lower, but often they are very different. The internet is full (no more addresses), so we need a new one (IPv6). In the mean time ISP's are giving most customers no more than one IP address (some have less: have to share). When one of your machines connects out, the Network Address Translator changes your IP to the public one. This is fine for most outgoing connections, but not for incoming. And is usually not noticed, by most users.

  • Thanks for your reply, strange thing is, is that the interface on the Firewall which is also the Gateway has the external IP address one above the one reported by the Trace route command.

  • All the IPs on the same sub-net will have similar addresses. So something like ?.?.?.x or ?.?.x.x where x changes. Therefore one higher is on the same subnet, traceroute does not always identify all of the nodes. Some are missed completely, some are anonymous.

Postfix configuration issue with fips on centos 7; mailgun relay

Image
Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
