Hello,
I have a server with multiple 4G modems with Squid running on it, the 4G
modems get an internal private IP that is dynamic (unfortunately this
can't be changed),
I set up Squid to use the interfaces as follows:
tcp_outgoing_address <some_ip>
The configuration works well and everything works great, however,
whenever I restart one of the modems (I have many, and I restart them a
lot), I get a new internal private IP, and I need to reconfigure Squid,
this means that I will be running "squid -k reconfigure" multiple times
a minute.
Will this have a bad effect on Squid and traffic (I understand this does
not cause Squid to restart)? What is my alternative?
Alternative is to **not** configure Squid with a static IP.
You could use an outgoing TOS or NFMARK from Squid. The OS networking
rules can select routes based on that.
OR, if the src-IP has to change based on the modem being used. You could
use the TOS/MARK in src-NAT rules before route selection - those being
the point reconfigured instead of Squid.
