Re: Multiple internet providers

Hi!

Thank for answer!

No, I have provider delegated adresses in any case. And I have few additional
uestions on the topic:

1. What is the "der Mouse srt interface"? I've met the term on some old
threads.

2. Can ipfilter do source-based routing? I've met some rules construction, like:

pass out quick pppoe1 fastroute to pppoe2 from 2001:db8:2222::/48 to any

or 

pass out quick on bge126000 to nge125000:192.168.125.1 from 192.168.186.0/24 to 
any

Didn't try, maybe next weekend.
