Sophos XG HA PPPoE slow reconnect

someone else will know more, but I'm sure it's a known thing that PPPoE (or was it oA?) won't auto reconnect. You have to do it manually or reboot Sophos after the connection drops.

I don't know if this is only related to pppoe - we're having a different setup but with only one WAN Gateway on XG. The GW is an other LAN router.

Whenever we have HA failover, manually or by fault, and the secondary node becomes active, the internal network is up after about 1-3 minutes but WAN traffic is only possible after waiting 10-15 minutes.

ahh this sounds different then, hopefully someone else can help.

Hi, Svigelj Levi1 Technically it is not possible to have a PPPoE connection from both PRIM and AUX on the same link at the same time, and considering that fact PPPoE configuration on XG with HA setup is only supported with Active-Passive mode.

Now during HA failover PPPoE will disconnect as PPPoE is not running on the AUX machine and AUX (node) which has taken the role of primary will start the PPPoE connection again with ISP modems. During this disconnection now syslog.log will give more clues why the delay happens in reconnecting PPPoE by analyzing the PPPoE handshake status.

Note: In the past, with such issues, it was observed that the new primary node (after HA failover) was not receiving PADI packets response because of MAC binding at the ISP end/ ISP modem.
