Brilliant. That works, thanks. I had tried the same with a space
separator instead of a comma and f2b wouldn't load the jail.
I do find it odd that the normal way of specifying bantime does not work
with this jail.

On your {sshd] jail, use:
action = iptables-ipset-proto6-allports[*name*=sshd,*bantime*=86400]
Look at /etc/fail2ban/action.d/iptables-ipset-proto6-allports.conf for
actionban:
actionban = ipset add <*ipmset*> <ip> timeout <*bantime*> -exist
[Init]
bantime = 600 <-- this default is used if not on the invocation line*
ipmset* = f2b-<*name*>
You pass the <arguments> in the invocation [...,bantime=86400].
<ipmset> is created in the [Init] section with the ipmset =
from the passed <name> argument. Fail2ban supplies <ip>.

Hello Bill,
The countdown is working correctly but from 600 which is the
"bantime" setting in iptables-ipset-proto6-allports.conf. I am
wanting to override it on a per-jail basis, in this example to 86400.
It seems that iptables-ipset-proto6-allports.conf does not use the
override. I can override it in iptables-ipset-proto6-allports.local,
but this is an override for all jails using this action.
Do you know how to achieve this?
Thanks,
Nick

Timeout here is the *default* timeout. Look at the actual entry.
It should be counting down
between the two ipset commands.
ipset -L | grep -e Name -e 8.8.8.8
Where 8.8.8.8 is the actual IP address.

I've just noticed that the sshd jail is not using the bantime set
in a configlet in /etc/fail2ban/jail.d:
[sshd]
enabled = true
bantime = 86400

[root@dynamicvpn ~]# ipset list f2b-sshd -terse

I can see there is a a timeout in
iptables-ipset-proto6-allports.conf but changing this, e.g, with
.local file, changes it for all jails. Is it possible to set the
timeout for this action on a per-jail basis?
I'm using f2b 0.10.5.
