I have a problem with repo-broswer and checkout with TortoiseSVN(1.7) over VPN(IPsec). For example when I want to check-out repository, all begins OK, but after few seconds(sometimes 10 files, sometimes 20, 50) speed drops to 0 Bytes/s and everything stops. In this moment I can not ping server with SVN server, or anything else. But when I close checkout window after few seconds everything is OK. Other SVN actions allways works fine(update, commit, revision graph, log), also I can download files from shares,... The only thing which does not work over my VPN is really SVN repo-browser and checkout... communication with SVN server on LAN without VPN works fine. Please help me.
server: Windows server 2003, Visual SVN server 2.5
client: Windows 7 Ultimate, Tortoise SVN 1.7.7
