nonakaです
参考になるかわかりませんが
eth0側とeth1側は異なるネットワークのためブリッジ接続やハブのような機能では異なるネットワーク間の通信はできないと思います。
異なるネットワーク間通信でしたら「ルーティング」や「IPマスカレード」について調べてみたらどうでしょう
千葉さんの情報にあるネットワーク環境ですとVine4.2をPCルータ化しWinpc1側にはeth0のIPをgatewayとしWinpc3側はeth1のIPをgatewayとするのも方法の一つだと思います。
iptablesでeth0->192.168.1.10あてにきたパケットをeth1->192.168.2.20側へ転送というようなかんじでしょうか
