Just bought a WRT54G V4. Is there are firmware that will: - pull in the 2 WAN IPs assigned to me by my ISP - 1st WAN IP assigned to wired connections only - 2nd WAN IP assigned to wireless connections only - PCs in the wired network can see each other - PCs in the wireless network can see each other - PCs in the wired and wireless connections should NOT see each other - they should be totally separately networks with their own WAN IPs. Can this be done with a single WRT54G? How? Thanks.
