[Shorewall-users] Multi-ISP: [controlling] source address in ipv6

[Brian J. M. <br...@in...>]

Hi,

I know in Shorewall for IPv4 there are rules to ensure that the correct
source address is being used for each of the interfaces in a Multi-ISP
configuration.

Does such a thing exist for IPv6?  Maybe Shorewall is the wrong tool?

I have a problem where my router seems to be using an address from a
different interface when sending ICMP6 packets out.  To clarify, I have
two IPv6 providers with two different IP addresses for them on my end.
At some point on interface A, the (Linux, Shorewall) router will need to
send an ICMP6 "packet too big" packet to a remote.  The problem is that
when it does this it is sending it from the IP address on interface B.

Can I solve this with Shorewall6?

Cheers,
b.
