Thanks. Will check supernetting option. As per another suggestion, I tried matching the encryption domains on both end. The PIX end is simple with two networks. But Checkpoint end encryption domain is common for all site-to-site and remote access clients and is a huge list of all IPs/networks inside the network which need to be accessed over VPN from outside. Hence it is difficult to match the encryption domain on both sides of the vpn tunnel. Any ideas on this?
