RT57iのVPN接続でLAN内につながらない
PC1 -> RTX1100 -> Internet -> RT57i -> PC2
RT57iでpptp設定を行いPC1から接続はできましたが
PC1からPC２へpingが通りません。
1:PC1からRT57iのVPN接続は完了している
2:PC1からRT57iへのpingは通る
3:RT57iからPC2へpingは通る
4:PC1からPC2へのpingは通らない
RTX1100 : 192.168.12.0/24
PC1 : 192.168.12.4
(pptpで割り振られたIP:192.168.0.14)
RT57i : 192.168.0.0/24
PC2 : 192.168.0.101
問題点はどこにありますでしょうか？

お礼
ご回答いただきありがとうございます！ なるほど。TCP/UDP以外のプロトコルではそれぞれTCP/UDPのポート番号と似たようなもので“NAT越え”を実現しているんですね。 これですっきりしました。ありがとうございました。
