It is. But getting the details right isn't trivial.

If I understand you right, then you only have one route to the Internet (the
first connection). The second isn't a route to "the Internet"; it is a route
to some a.b.c.d/29 network. Or ... if that second network is connected to
the Internet ... does *its* gateway router know that it has a route back to
your (I assume) Debian-based router?

Do you mean the echo-request can go in on one interface but the echo-reply
come out on the other? The answer is that it can, but whether it will
depends a lot on the details of your routing and firewalling setup (and the
routing and firewalling setups of the networks the two connections go to).
Based on your sketchy description, that's about all I can say for now,
without a good bit more detail on the actual routing and firewalling setups
involved.
