Hi, I have been using rt_rules to force certain traffic out one or the
other of my iSP's, and it has worked will for years. I seem to have done
"something" that has caused the following behavior.
One ISP is vlan5 and it's flaky. The other is vlan7 and it's mostly stable.
The two ISP's are set up w

It sounds like an O
Thanks Justin, yes it would be a good idea to manage my configs ...
This is Ubuntu 20.04 with netplan. vlan5 is a dhcp interface however vlan7
is static and produces the same behavior.
No it doesn't seem like shorewall is doing it. /var/log/shorewall-init.log
doesn't record anything. For now I wi

Thank you Erich. I would have suspected DHCP, except that vlan7 has a
static IP in Netplan and if I flip it down and up again, there is a static
route added for its gateway to the ip route table main, just as happens
with a recycle of vlan5 which is DHCP.
A mystery. I have a working bypass for now

Thanks Tuomo.
The interfaces of course require a gateway since they are not
point-to-point.
Today I disabled foolsm so I am sure those scripts are not doing anything.
I cannot guess what other system component could be reacting to a change in
interface status and creating a default route in table

You missed the point. Interface scripts must not add gateway when you
do multi-isp. If you down/up interface and scripting add gateway, then
run
Thanks again. I discovered a source that I had not thought about before:
gateways defined along with static IP's in the netplan configuration; I
removed those.
The other source is dhcp. I removed "routers" from the "request" list in
dhclient.conf and to be sure added a script under
/etc/dhcp/dhclie
