Unstable connection to VPN

[Konov Leonid]

I have a problem with nm-openconnect vpn, browser and my internet provider.
When I connect to VPN, I get connection via terminal, but I have not connection via browser (error time out).

I have configured VPN connection as my Company says in instruction.

I can establish VPN connection in browser one time by following steps:
1) In Network Manager on Proxy tab I should set mark "browser-only" and I should change configuration between No proxy and Automatic proxy. If I don't change configuration between No proxy and Automatic proxy - VPN connection don't establish. (On Windows I don't configuration any proxy. With AnyConnect I don't configuration any proxy)
2) In Ubuntu configuration menu (aka Windows Start) - Network - Proxy - I should change exact setting, as in step 1. If I set No proxy, I shold set No proxy there. If I set Automatic proxy, I shold set Automatic proxy there.
3) Then I can connect VPN one time.
4) If I disconnect, reboot computer - I should go steps 1, 2, 3.

I solve problem by installing Cisco AnyConnect.
