# WHATPORT(1148)

## NAME

port 1148 — Elfiq Replication Service — Registered in 2005 for Elfiq link-balancer appliances to replicate state between units.

Protocol: TCP  
IANA registry

## DESCRIPTION

IANA assigns 1148 to elfiq-repl, "Elfiq Replication Service", registered by Elfiq for its link-balancing appliances. The port carries replication traffic between paired units rather than any client-facing service, so it appears only on networks running that hardware. Nmap's dataset finds it open very rarely.

## EXPOSURE

**Do not expose.** Appliance-to-appliance replication is a trust channel between cluster members; restrict it to the dedicated link between the units.

## CHECK

```sh
nmap -Pn -p 1148 -sV TARGET
```
