My bet is, given your arp table, that you want a /24 subnet mask, ie,
255.255.255.0.  So try this and tell me what happens:

# ifconfig eth0 90.0.0.89 netmask 255.255.255.0 broadcast 90.0.0.255
# ifconfig eth1 90.0.0.88 netmask 255.255.255.0 broadcast 90.0.0.255

Well, having both interfaces on the same /24 isn't going to get you what
you're after.  The idea of a firewall/router is to have one interface on a
private subnet (say, 10.0.0.0/24) and another on a public subnet
(your 90.0.0.0/24 for instance.)  Then you "route" between them.
