提取nat server行的字符ip route-static 10.124.188.0 255.255.255.0 10.220.54.30 ip route-static 10.220.59.64 255.255.255.192 10.220.54.30 ip route-static 10.220.73.0 255.255.255.192 10.220.54.30 # firewall detect ftp # nat server MOREN-NAT-1 zone untrust global

对于给定的文本，提取nat server行的字符可以使用正则表达式进行匹配。以下是一个示例代码，演示如何提取这些行:

import re

text = """
ip route-static 10.124.188.0 255.255.255.0 10.220.54.30
ip route-static 10.220.59.64 255.255.255.192 10.220.54.30
ip route-static 10.220.73.0 255.255.255.192 10.220.54.30
# firewall detect ftp
nat server MOREN-NAT-1 zone untrust global
"""

pattern = r"nat server.*"

matches = re.findall(pattern, text)

for match in matches:
    print(match)

运行上述代码，输出将是:

nat server MOREN-NAT-1 zone untrust global

这样，你就提取到了nat server行的字符。请注意，这里使用的是简单的正则表达式模式，可以根据实际情况进行调整。
